There is a Microsoft account associated with each one of these users, where they store emails, calendars, contacts, OneDrive files, Teams conversations, and much more. When these organisations undergo mergers, acquisitions, tenant consolidation, and look forward to restructuring the business, they perform cross-tenant migration. But specifically, for an enterprise-level migration project, the number of users might increase to 250 users or more. As a result, the migration process is not limited to creating accounts in another tenant.

Whereas, when it comes to organisational projects, this number might increase to 250 or more users. As the number of users increases, so does the complexity of migration because this migration would now involve accounts, mailboxes, identities, licences, permissions, and data. Thus, it becomes important to correctly coordinate, map, and validate both tenants accurately.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Key differences lie in scale \u2013 rather than the migration concept itself. When migrating on an enterprise level, dividing 250 users into carefully managed batches is essential &#8211; beginning with a test group to see how well it works out and fixing any problems that arise. Only after validating all your migrated information will you apply this method to subsequent groups safely.<\/p>\n\n\n\n<h2 class=\"wp-block-heading main_heading\"><span class=\"ez-toc-section\" id=\"What_Data_Needs_to_Be_Migrated\"><\/span>What Data Needs to Be Migrated?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">For 250 users, create an inventory of the workloads involved.<\/p>\n\n\n\n<div style=\"margin: 20px 0;\">\n<table style=\"border-collapse: collapse; border: 1px solid #555555;\">\n<tbody>\n<tr>\n<td style=\"border: 1px solid #555; padding: 8px;\"><strong>Workloads&nbsp;<\/strong><\/td>\n<td style=\"border: 1px solid #555; padding: 8px;\"><strong>Data to Consider&nbsp;<\/strong><\/td>\n<\/tr>\n<tr>\n<td style=\"border: 1px solid #555; padding: 8px;\">Exchange Online<\/td>\n<td style=\"border: 1px solid #555; padding: 8px;\">Emails, attachments, calendars, contacts, tasks &amp; notes<\/td>\n<\/tr>\n<tr>\n<td style=\"border: 1px solid #555; padding: 8px;\">SharePoint<\/td>\n<td style=\"border: 1px solid #555; padding: 8px;\">Sites, libraries, documents, permissions<\/td>\n<\/tr>\n<tr>\n<td style=\"border: 1px solid #555; padding: 8px;\">Teams<\/td>\n<td style=\"border: 1px solid #555; padding: 8px;\">Chats, meetings, teams, channels, files<\/td>\n<\/tr>\n<tr>\n<td style=\"border: 1px solid #555; padding: 8px;\">OneDrive<\/td>\n<td style=\"border: 1px solid #555; padding: 8px;\">Files, folders, permissions, sharing<\/td>\n<\/tr>\n<tr>\n<td style=\"border: 1px solid #555; padding: 8px;\">Groups<\/td>\n<td style=\"border: 1px solid #555; padding: 8px;\">Membership, ownership, group resources<\/td>\n<\/tr>\n<tr>\n<td style=\"border: 1px solid #555; padding: 8px;\">Identities<\/td>\n<td style=\"border: 1px solid #555; padding: 8px;\">Users, UPNs, SMTP addresses, mappings<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading main_heading\"><span class=\"ez-toc-section\" id=\"Exactly_How_Much_Data_Do_250_Users_Represent\"><\/span>Exactly How Much Data Do 250 Users Represent?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The number of users alone would not decide the complexity of the migration process. You can calculate the expected volume of data before you migrate 250 Microsoft 365 users to new tenant.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For instance, if each user has a 15 GB mailbox:<\/p>\n\n\n\n<div style=\"margin: 20px 0;\">\n<table style=\"border-collapse: collapse; border: 1px solid #555555;\">\n<tbody>\n<tr>\n<td style=\"border: 1px solid #555; padding: 8px;\"><strong>250 \u00d7 15 GB = 3.75 TB<\/strong><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n\n\n\n<p class=\"wp-block-paragraph\">At the same time, if each user has 30 GB of OneDrive data to migrate,<\/p>\n\n\n\n<div style=\"margin: 20px 0;\">\n<table style=\"border-collapse: collapse; border: 1px solid #555555;\">\n<tbody>\n<tr>\n<td style=\"border: 1px solid #555; padding: 8px;\"><strong>250 \u00d7 30 GB = 7.5 TB<\/strong><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, the combined data of Exchange Online and OneDrive would be considered and would approximately result in 11.25 TB of data.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>*This is only an example. Actual mailbox and OneDrive sizes should be obtained from the source tenant.*<\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-heading main_heading\"><span class=\"ez-toc-section\" id=\"What_to_Check_Before_You_Move_250_Office_365_Users_to_New_Tenant\"><\/span>What to Check Before You Move 250 Office 365 Users to New Tenant?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">There are certain parameters that one needs to consider before they proceed to the migration process. Make sure all the necessary steps in the <a href=\"https:\/\/www.arysontechnologies.com\/blog\/microsoft-365-migration-checklist\/\" target=\"_blank\" rel=\"noopener\">Microsoft 365 cross-tenant migration checklist<\/a> are fulfilled before you proceed further.

Create a User Mapping<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The first step is to prepare a source-destination (A-B) mapping like the ones below.<\/p>\n\n\n\n<div style=\"margin: 20px 0;\">\n<table style=\"border-collapse: collapse; border: 1px solid #555555;\">\n<tbody>\n<tr>\n<td style=\"border: 1px solid #555; padding: 8px;\"><strong>Source<\/strong><\/td>\n<td style=\"border: 1px solid #555; padding: 8px;\"><strong>Destination<\/strong><\/td>\n<\/tr>\n<tr>\n<td style=\"border: 1px solid #555; padding: 8px;\">john@companyA.com<\/td>\n<td style=\"border: 1px solid #555; padding: 8px;\">john@companyB.com<\/td>\n<\/tr>\n<tr>\n<td style=\"border: 1px solid #555; padding: 8px;\">sara@companyA.com<\/td>\n<td style=\"border: 1px solid #555; padding: 8px;\">sara@companyB.com<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n\n\n\n<p class=\"wp-block-paragraph\">During this process, recording every user&#8217;s UPN, SMTP address, mailbox size, OneDrive size, license information, group memberships, Teams memberships, and significant permissions becomes very critical indeed.<\/p>\n\n\n\n<h3 class=\"wp-block-heading main_heading\"><span class=\"ez-toc-section\" id=\"2_Check_Licences\"><\/span>2. Check Licences<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Review the licences available in both tenants.

This software consists of a <em>CSV import feature<\/em> along with an admin mode to authenticate the source and destination accounts. The admin mode lets enterprises migrate data items from all sub-users in one go. Whereas the CSV import feature enables bulk migration capability &amp; allows organisations to import a single CSV file containing multiple users. Whether it be <em>250 users or even more than that<\/em>, this software makes sure to migrate data within a few clicks, that too, without losing data integrity.<\/p>\n\n\n\n<h4 class=\"wp-block-heading main_heading\"><span class=\"ez-toc-section\" id=\"Simplified_Steps_to_Migrate_250_Microsoft_365_Users_to_New_Tenant-2\"><\/span>Simplified Steps to Migrate 250 Microsoft 365 Users to New Tenant<span class=\"ez-toc-section-end\"><\/span><\/h4>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Download, set up, and execute <strong>Aryson&#8217;s Tenant-to-Tenant Migration Tool<\/strong>.<\/li>\n\n\n\n<li>Then select which <strong>workloads <\/strong>are essential for your migration needs.<\/li>\n\n\n\n<li><strong>Connect to the source tenant<\/strong> via Modern Auth or client ID or secret.<\/li>\n\n\n\n<li>Select the required <strong>mailboxes, sites, OneDrive data, <\/strong>or <a href=\"https:\/\/www.arysontechnologies.com\/blog\/migrate-microsoft-teams-between-tenants\/\" target=\"_blank\" rel=\"noopener\"><strong>Teams<\/strong><\/a> from the displayed ones.<\/li>\n\n\n\n<li><strong>Log in to the destination tenant<\/strong> via Admin mode or load users with CSV import.<\/li>\n\n\n\n<li><strong>Map source-to-destination user accounts<\/strong> and apply date or folder filters.<\/li>\n\n\n\n<li>Click <strong>Start Migration<\/strong> to begin the cross-tenant transfer.<\/li>\n\n\n\n<li>After migration, <strong>monitor the migration process<\/strong> via the progress bar.<\/li>\n<\/ol>\n\n\n\n<div style=\"border: 2px solid #4a6fa5; padding: 10px; margin-top: 10px; margin-bottom: 10px; border-radius: 25px; background-color: #f4f7fb; font-family: Arial, sans-serif; font-size: 16px; line-height: 1.5; text-align: left;\">However, the above steps will help you migrate data that too without investing much time; it is recommended to read the <a href=\"https:\/\/www.arysontechnologies.com\/office-365\/migration\/how-it-works.html\" target=\"_blank\" rel=\"noopener\"><strong>complete documentation<\/strong><\/a> of the software.

Before starting your migration process, planning data transfer is very important &#8211; both at the user level and for your workloads. Users may start by mapping 250 identities and then calculating the total <strong><a href=\"https:\/\/www.arysontechnologies.com\/blog\/export-exchange-online-archive-to-local-pst\/\" target=\"_blank\" rel=\"noopener\">Exchange<\/a><\/strong>, <strong><a href=\"https:\/\/www.arysontechnologies.com\/blog\/transfer-files-from-onedrive-to-google-drive\/\" target=\"_blank\" rel=\"noopener\">OneDrive<\/a><\/strong>, <strong><a href=\"https:\/\/www.arysontechnologies.com\/blog\/migrate-sharepoint-online-sub-sites-and-their-structure\/\" target=\"_blank\" rel=\"noopener\">SharePoint<\/a><\/strong>, and Teams data. Then, proceed with the pilot migration via the manual approach or the professional method discussed above, and apply the suitable approach to the entire dataset. To minimise throttling and quickly migrate all 250 users, it is recommended to use the software\u2019s CSV import feature to achieve a successful migration.<\/p>\n\n\n\n<h3 class=\"wp-block-heading faq-main_heading\"><span class=\"ez-toc-section\" id=\"Frequently_Asked_Questions\"><\/span>Frequently Asked Questions<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<div class=\"schema-faq wp-block-yoast-faq-block\"><div class=\"schema-faq-section\" id=\"faq-question-1791450084472\"><strong class=\"schema-faq-question\"><strong>Q.1 How do I migrate 250 Microsoft 365 users to a new tenant?<\/strong><\/strong> <p class=\"schema-faq-answer\"><strong>Ans:<\/strong> First, you must plan the migration process, perform all the pre-migration steps, and use either the manual method or the professional one to begin the process. However, both methods work well; it is highly recommended to use the software for quick and secure migration.\u00a0<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1791450088999\"><strong class=\"schema-faq-question\"><strong>Q.2. What Microsoft 365 data can be migrated between two tenants?<\/strong><\/strong> <p class=\"schema-faq-answer\"><strong>Ans:<\/strong> When it comes to the software, it can migrate Exchange Online mailboxes, OneDrive, SharePoint, and Teams data between tenants, that too without any data loss.\u00a0<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1791450089576\"><strong class=\"schema-faq-question\"><strong>Q.3. How much data can 250 Microsoft 365 users contain?<\/strong><\/strong> <p class=\"schema-faq-answer\"><strong>Ans:<\/strong> Uncertain. There doesn&#8217;t exist any particular number or fixed volume of data for 250 users. Rather, the total data size largely depends on the individual mailbox, OneDrive, SharePoint, and other workloads.\u00a0<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1791450090033\"><strong class=\"schema-faq-question\"><strong>Q.4. Can Aryson migrate multiple Microsoft 365 users in bulk?<\/strong><\/strong> <p class=\"schema-faq-answer\"><strong>Ans:<\/strong> Yes. When it comes to the software, it can migrate multiple users at the same time via its CSV import feature. With the help of this functionality, large firms can load multiple users simultaneously and support bulk migration. Thus, there is no need to configure each account individually.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1791450090592\"><strong class=\"schema-faq-question\"><strong>Q.5. Does the Aryson tool support admin-level authentication for tenant migration?<\/strong><\/strong> <p class=\"schema-faq-answer\"><strong>Ans:<\/strong> Yes. The software allows users to log in to their tenant account via Admin Mode and authenticate the source and destination accounts. They just have to select data from multiple sub-users to migrate data.\u00a0<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1791450091136\"><strong class=\"schema-faq-question\"><strong>Q.6. Can I migrate only selected data from a Microsoft 365 user?<\/strong><\/strong> <p class=\"schema-faq-answer\"><strong>Ans:<\/strong> Yes. With the help of the Aryson Tenant to Tenant Migration Tool, you can easily migrate selected data using the date range and other folder filters provided by the software.\u00a0<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1791450092248\"><strong class=\"schema-faq-question\"><strong>Q.7. Why should a 250-user migration be performed in batches?<\/strong><\/strong> <p class=\"schema-faq-answer\"><strong>Ans:<\/strong> It is considered a better practice to perform a migration on 250 users or more in batches, rather than performing a cutover migration. For this, first migrate a test pilot batch and monitor the progress closely. If there are zero errors, perform migration on the remaining dataset. However, if you use professional software, you may eliminate all this, migrate 250 users in bulk, and save time.\u00a0<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1791450092784\"><strong class=\"schema-faq-question\"><strong>Q.8. Can I monitor the migration progress for 250 users?<\/strong><\/strong> <p class=\"schema-faq-answer\"><strong>Ans:<\/strong> Yes. The monitoring panel of the Aryson Tenant-to-Tenant Migration Tool allows you to track the migration process. You may check the total number of migrated folders, the failed ones, and the ongoing migration at every step.\u00a0<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1791450093281\"><strong class=\"schema-faq-question\"><strong>Q.9 What is cross-tenant user data migration in Microsoft 365?<\/strong><\/strong> <p class=\"schema-faq-answer\"><strong>Ans:<\/strong> It is the process of moving the workload data from one tenant account to another in a Microsoft 365 environment. These workloads might include Exchange Online mailboxes, SharePoint sites and document libraries, OneDrive data and Teams conversations.\u00a0<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1791450093896\"><strong class=\"schema-faq-question\"><strong>Q.10 Which is the best tool to migrate 250+ Microsoft 365 users from one tenant to another?<\/strong><\/strong> <p class=\"schema-faq-answer\"><strong>Ans:<\/strong> The Aryson Tenant-to-Tenant Migration Tool is the best tool to migrate 250+ Microsoft 365 users from one tenant to another. This is because this software comes with both CSV file importing and admin login. On top of that, it also provides users with a free demo version that can be used to evaluate the software\u2019s performance.<strong>\u00a0<\/strong><\/p> <\/div> <\/div>\n\n\n<div class=\"kk-star-ratings kksr-auto kksr-align-left kksr-valign-bottom\"\n    data-payload='{&quot;align&quot;:&quot;left&quot;,&quot;id&quot;:&quot;7629&quot;,&quot;slug&quot;:&quot;default&quot;,&quot;valign&quot;:&quot;bottom&quot;,&quot;ignore&quot;:&quot;&quot;,&quot;reference&quot;:&quot;auto&quot;,&quot;class&quot;:&quot;&quot;,&quot;count&quot;:&quot;0&quot;,&quot;legendonly&quot;:&quot;&quot;,&quot;readonly&quot;:&quot;&quot;,&quot;score&quot;:&quot;0&quot;,&quot;starsonly&quot;:&quot;&quot;,&quot;best&quot;:&quot;5&quot;,&quot;gap&quot;:&quot;5&quot;,&quot;greet&quot;:&quot;Rate this post&quot;,&quot;legend&quot;:&quot;0\\\/5 - (0 votes)&quot;,&quot;size&quot;:&quot;24&quot;,&quot;title&quot;:&quot;Migrate 250 Microsoft 365 Users to New Tenant: Secure Tenant-to-Tenant Migration for Enterprises&quot;,&quot;width&quot;:&quot;0&quot;,&quot;_legend&quot;:&quot;{score}\\\/{best} - ({count} {votes})&quot;,&quot;font_factor&quot;:&quot;1.25&quot;}'>\n            \n<div class=\"kksr-stars\">\n    \n<div class=\"kksr-stars-inactive\">\n            <div class=\"kksr-star\" data-star=\"1\" style=\"padding-right: 5px\">\n            \n\n<div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n            <div class=\"kksr-star\" data-star=\"2\" style=\"padding-right: 5px\">\n            \n\n<div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n            <div class=\"kksr-star\" data-star=\"3\" style=\"padding-right: 5px\">\n            \n\n<div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n            <div class=\"kksr-star\" data-star=\"4\" style=\"padding-right: 5px\">\n            \n\n<div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n            <div class=\"kksr-star\" data-star=\"5\" style=\"padding-right: 5px\">\n            \n\n<div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n    <\/div>\n    \n<div class=\"kksr-stars-active\" style=\"width: 0px;\">\n            <div class=\"kksr-star\" style=\"padding-right: 5px\">\n            \n\n<div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n            <div class=\"kksr-star\" style=\"padding-right: 5px\">\n            \n\n<div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n            <div class=\"kksr-star\" style=\"padding-right: 5px\">\n            \n\n<div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n            <div class=\"kksr-star\" style=\"padding-right: 5px\">\n            \n\n<div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n            <div class=\"kksr-star\" style=\"padding-right: 5px\">\n            \n\n<div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n    <\/div>\n<\/div>\n                \n\n<div class=\"kksr-legend\" style=\"font-size: 19.2px;\">\n            <span class=\"kksr-muted\">Rate this post<\/span>\n    <\/div>\n    <\/div>\n","protected":false},"excerpt":{"rendered":"<p>Migration Overview: Large firms and enterprises have a large number of employees.
