Over the last few years, Office 365 has become the go-to productivity platform for businesses of all sizes. As organizations continue to embrace Office 365, the need for tenant-to-tenant migrations has increased. Although Office 365 provides a number of built-in tools for migrating users and data, the process can still be complex and time-consuming.
To help simplify the Office 365 tenant to tenant migration process, we’ve put together a step-by-step guide. This guide covers everything from planning and preparation to execution and post-migration tasks. By following these steps, you can ensure a successful migration with minimal disruption to your users.
A tenant in Microsoft 365 is a unique environment of Office 365 services. It is a specific location such as Europe or North America to store organization data. It contains organization data including Office 365 Mailboxes, Documents and Sites on SharePoint, files data on OneDrive, Teams etc. A tenant administrator can use all the features given in the subscription. In business-merger scenarios, the mailboxes need to be moved to another tenant. The migration is not a linear process; you need to do some preparation, meet some prerequisites, and own licenses.
So, here we are going to discuss some basics that can help you migrate mailboxes from one Microsoft 365 tenant to another. Also, here we’ll talk about how you can plan the migration.
Migrate mailboxes, public folders, & archive mailboxes from one Microsoft 365 tenant to another using a professional Kernel Office 365 Migration Tool.
A Microsoft 365 tenant to tenant migration may present various challenges depending on your migrations scenario. Usually, tenant to tenant migrations are done during business acquisitions, mergers, or divestitures. Consequently, you have different migration patterns like a one-time migration, a phased migration, or a split flow/tenant move.
The Microsoft 365 tenant to tenant migration is performed using PowerShell scripts or third-party tools. Before that, there is an Office 365 Pre & Post Migration checklist you should keep in mind.
Step 1. Domain Preparation
Depending on your migration pattern, you may have various considerations before domain preparation. Usual scenarios are:
Based on your requirements, prepare the domain with the following steps:
Step 2. Domain verification
Make sure the domain is in use with only one tenant. Otherwise, the verification will fail.
After performing these steps, it will take around 72 hours for the change to be seen.
Step 3. Migration Scheduling
Step 4. Migration Stage
Stop inbound mail flow
Stop inbound mail flow to the source tenant by changing the primary MS record to an unreachable value or by using a third-party service. As you have noted the lowest value of TTL on the MX record (of primary email domain) in your preparation step, you can plan the time of this step easily.
Source tenant preparation
Before moving the Office 365 mailbox to another tenant, the primary mail domain should be erased from all objects in the source tenant.
Preparing the target domain
It involves verifying the source tenant in the target domain (one hour after the previous step).
Now it is time to decide on the migration method. You can also decide on the type and amount of data to be migrated. Migration can be accomplished using PowerShell scripts. However, this method is very complex even if you are an Exchange expert. You will have to do a thorough preparation prior to migration so that you won’t mess up with cmdlets or steps. Also, it is time-consuming even if you assign multiple hands to complete the task. So, third-party migration tools are recommended as they offer complete control over the migration along with quick and efficient processes automatically.
