What do you wish you had backed up before moving from Exchange on-prem to Microsoft 365?
One thing many IT teams wish they had backed up before moving from Exchange on-premises to Microsoft 365 is everything beyond just mailboxes. While emails are the obvious priority, overlooked components like public folders, shared mailboxes, archive mailboxes, and mailbox permissions often create post-migration headaches. Additionally, organizations frequently underestimate the importance of backing up calendar data, contact lists, and delegation settings, which are critical for daily operations.
Another commonly missed area is legacy data stored in PST files across user systems. Without consolidating and backing these up, valuable historical communication can be lost. System configurations, transport rules, and retention policies are also vital, as recreating them manually can be time-consuming and error-prone.
Finally, Aryson Office 365 having a full backup ensures a fallback option in case of migration errors or data corruption. A comprehensive pre-migration backup strategy not only protects data integrity but also ensures business continuity and a smoother transition to the cloud environment.
