The right migration method depends on the type and amount of data you need to transfer. However, IMAP can work for email-only migrations, while Google Workspace migration methods can support additional data such as contacts and calendars. <\/p>\n<p>Before you start, audit the source accounts, prepare Microsoft 365, &#038; test the migration with a small group. For larger migrations that also involve Google Drive &#038; mapping, or detailed reports, a Cigati Google Workspace Backup Tool can provide additional migration options.<\/p>\n<div class=\"faq-n my-4\">\n<h4 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Frequently_Asked_Questions\"><\/span>Frequently Asked Questions<span class=\"ez-toc-section-end\"><\/span><\/h4>\n<div class=\"schema-faq wp-block-yoast-faq-block\">\n\n\n<div class=\"schema-faq wp-block-yoast-faq-block\"><div class=\"schema-faq-section\" id=\"faq-question-1786972432660\"><strong class=\"schema-faq-question\"><strong>Q-1.
