If your organisation has a small dataset and a technically confident administrator, the manual PowerShell-based batch migration can work. But, it requires the user to carefully perform the prerequisites &amp; the mandatory downtime window. But when data volume is large, or you want to avoid scripting risks &amp; rollback complications, using automated software is the faster and safer choice. Choose a method that protects your folder data and does not make the process more disruptive than it needs to be &#8211; and act before October 2025 if you are still on Exchange 2010.<\/p>\n<h2 class=\"faq-main_heading\"><span class=\"ez-toc-section\" id=\"FAQs\"><\/span>FAQs<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n<div class=\"schema-faq wp-block-yoast-faq-block\"><div class=\"schema-faq-section\" id=\"faq-question-1776950194578\"><strong class=\"schema-faq-question\"><strong>Q.1. What are Legacy Public Folders in Exchange?<\/strong><\/strong> <p class=\"schema-faq-answer\"><strong>Ans: <\/strong>Legacy Public Folders are shared repositories in Exchange 2010 and earlier.
