Upcoming Webinar: How to migrate data between Office 365 tenants

21 Jun 2018 by Mike Weaver

Quadrotech and Content and Code are hosting a webinar together on June 28 at 2 PM BST. Register now.

Organizations are in constant change. Mergers, Acquisitions, and Divestitures (MA&D) flood the Business section and headlines. With increasing regulation, many organizations are having a need to move their data into country-specific, or Government-dedicated tenants. As a technologist that focuses on MA&D, we are constantly accommodating this. However, when it comes to Office 365, there is an extra level of complexity. Microsoft has designed the service to ensure that data never crosses from one tenant to another, without proper sharing and trusts. While this design for a pooled service is logical, when it comes to combining tenants, it is a nightmare.

At Microsoft Ignite 2017, we heard many announcements in this space to try to help make the process of combining tenants easier. These enhancements have had immediate effect and have continued to dribble out over the year.

On June 28th at 2 PM BST (9 AM ET), Microsoft MVP Steve Goodwin and I will host a webinar on how to combine multiple tenants. These projects can be complex and stressful. We’ll cover, and go beyond the technical items, but also discuss the business impact, decisions to make, what is changing, and more. Steve and I will share our project experiences, take questions, and help you get prepared for your project!

We’ll also cover these two topics – issues with data volumes and speed, and guidance on Project Management activities.

Data Volume & Speed

When we performed migrations from on-premises systems into Office 365, users were moving from an environment with data limits, in most cases, and moved into an environment with essentially no limits. If we needed to provide users with a terabyte of storage, we somehow had to procure enough disk with our tight IT budgets. Instead we put reasonable storage limits in place and users had to clean up the items they didn’t need. With Office 365, the limits for storage are so high that many users will not come close to hitting them. This means there is little incentive for them to clean up. The side effect of this is users have a lot more data to move.

The available options to migrate data between tenants is not known for being fast. For example, 5GB an hour is considered a decent migration speed for an email migration stream for EWS, with less for an MRS (Mailbox Replication Service) move. Where users commonly have a lot more email, this can be a major math problem when doing the project.

In the session we will discuss ways to mitigate this issue.

Project Management Activities

Like all major projects, an experienced Project Manager is required. This professional is needed to help coordinate all different moving parts of the project. This project can have significant business impact if it is not done correctly. Technical and business teams need to be properly prepared to complete a successful project.

In our experience working on migration projects, we have seen both good and bad examples of how these projects are handled. During this section of the webinar we will review some of the best practices for Project Managers to assimilate into their plans.

During the session we will also cover the common hang-ups in these projects, including tips around Project Management activities and other organizational factors.

I hope you’ll join Quadrotech and Content and Code on June 28th! If you can’t make the live event, make sure to register anyways as we’ll send out a post-event recording.
