IMAP Migration Sync: One way or Two way? and integrity check?
I would need to do a IMAP migration sync from a cPanel-based Dovecot email server to Office 365/Exchange Online using the method shared in https://support.office.com/en-ie/article/migrate-other-types-of-imap-mailboxes-to-office-365-58890ccd-ce5e-4d94-be75-560a3b70a706. I have two questions: Does the IMAP migration sync, sync 1-way or 2-way? 1-way sync: any changes on the source server/mailbox will be implemented in O365 mailbox. 2-way sync: any changes on the source mailbox and/or O365 mailbox will be implemented in both source server/mailbox and in O365 and vice-versa How do I check the integrity of the migrated emails/batch? I see some people are reporting some issues with IMAP migration in forums. Just wanted to know if there are any methods of checking the integrity and completeness of the migrated data. Feel free to drop-in any tips or experiences in using IMAP Migration Sync in general/cPanel Email server/Dovecot Email server. Thanks,
