The manual migration of On-Premises Exchange to Office 365 is not a simple task to perform. Each step is crucial, and so one needs care and expertise to accomplish such migration. This blog is drafted for discussing the necessary pre and post Office 365 migration checklist to help users in performing accurate migration without any loss.
The pre-migration tasks which the user should perform to get a smooth on-premises Exchange to Office 365 migration are divided into points. Let us discuss them.
Planning and preparation start with proper communication among the organization members. Before starting the migration project, each user should have complete information about the migration plan, how it is going to be executed, and what will be the impacts and changes within the organization due to this migration. Other important considerations of pre-migration check are migration day, time frame, and resource management. The plan should be discussed among the members on a rough basis to get ideas from different brains, and after the brainstorming, the administrator should draft a proper project plan for the migration without any discrepancies in it. You can use the checklist prepared by Microsoft for effective premigration planning. You can add or modify this checklist according to your requirements.
Next pre-migration task is to prepare the inventory for the on-premises Exchange. The details you should have before the migration are:
Some checks and reviews are required on the current on-premises Exchange environment.
Before starting the migration, make sure that the data is ready. Some points to be check are:
It is the final task while planning the Office 365 migration. Set up your Office 365 accounts with the below-given considerations.
Once all the tasks in the pre-migration checklist are completed, perform the migration. You can use professional Exchange Migration tool to perform this task easily. After migrating all the desired data migrated to the Office 365 destination, ensure that the tasks in the next provided checklist (post-migration) are completed.
After Office 365 migration, the emails accounts of users need to be redirected to Office 365. Also, check the Outlook profile folders again and confirm whether the status is “This Folder Is Up To Date” for each folder.
The mailboxes migrated in Office 365 account must be assigned licenses as it will get disabled after a period of 30 days without any license assignment. So, for long term use, it is recommended to assign licenses to mailboxes as soon as possible.
Another important post-migration task is to configure Autodiscover DNS records in Office 365. Doing this would help the users to connect their user mailboxes to Outlook email clients as well as other mobile clients.
Once you are confirmed that the mailboxes have successfully moved to your Office 365 account, have assigned licenses, and everything is working fine, then you can decommission the old on-premises Exchange Server. However, it is suggested that you decommission it only when no synchronization is expected in the future with the source, and permanent migration to target is accomplished.
