Why Are Tenant to Tenant Migrations So Complicated?

8 Oct 2020 by Natalie Frith

By nature, migrations are situational and can prove to be a complicated undertaking depending on certain variables.

An Office 365 tenant to tenant migration is inherently complex, and a common question we’re frequently asked is: “Why is a tenant to tenant migration so much harder than on-prem to Office 365?”

Quadrotech’s Director of Enterprise Migrations, Mike Weaver, gives a great response in this short video:

If you look at the cause of the migration, you’ll find that these types of migrations happen frequently during mergers, acquisitions or divestitures. So, to begin with, the dynamics of migrating one ecosystem into another completely different ecosystem pose intricate challenges.

And even though your IT team may have successfully performed the initial migration from on-prem to Office 365 internally, a cross-tenant is not on the same playing field. It’s a different sport entirely, with many more challenges.

In comparison, when you’re on-prem, you have total control over your systems. This gives you a lot more flexibility to be able to customize things, open up firewall ports, and be creative with how you can move the data from one side to the other. In Office 365, there are certain restrictions that must be adhered to and migration methodology must be uniform, which can make things a little more difficult.

What makes this type of migration even more perplexing is the fact that many of the products within O365 were not created with migration in mind. This means that the migration options don’t exist altogether, they take longer to migrate, or they just don’t offer the full migration experience, with incompatibilities and impractical workarounds.

When all these considerations come to a head for the migration project, it means that there’s going to be a delicate dance performed during the migration to circumvent speedbumps and entire roadblocks. If you’ve done the dance before, you’re in a much better position to pull the migration off without a hitch. If you haven’t, and you want to minimize disruption and stick to your timeline, then you’ll definitely want someone in your corner who has experience.

At Quadrotech, we’ve done a lot of work to be creative in order to achieve fast, effective tenant to tenant migrations despite these restrictions with the service. Our Office 365 to Office 365 migration tool, methodology, and structured approach have been proven successful at the enterprise level and in some of the most complex environments.
