CASE STUDY

A short and safe landing for the complex tenant-to-tenant migration in airline separation

“Migrating between tenants can be tough, but using Power365 enabled just a few people to migrate lots of users in a very short time!”

— David Todd, Head of Technology, IT Naturally

The Challenge

UK based Binary Tree partner, IT Naturally was given the challenge to migrate one Microsoft Office 365 tenant with over 2,200 users to a new Office 365 tenant, and it wasn’t just the email users that were in scope, but also shared mailboxes, OneDrive, Microsoft Teams and SharePoint sites.

To give it that extra twist of complexity, this wasn’t a cloud only migration. Users have on-premises Active Directory accounts which are sync’d using Azure AD Connect, so IT Naturally also had to synchronize users to a new on-prem Active Directory forest and sync that to the new tenant, then the sync of the Office 365 data could take place. There were a lot of moving parts!

The Solution

The customer’s timeline was short and fixed due to business requirements. The project needed to be completed in about 6 weeks. As you’d expect of any large and responsible company, the customer also needed us to undertake this with minimal impact to the business users.

To deliver this, IT Naturally decided to use software from Binary Tree: Directory Sync Pro was used for the Active Directory forest sync, copying across users (with their passwords), contacts and groups.

Directory Sync Pro was used for the Active Directory forest sync, copying across users (with their passwords), contacts and groups.

Power365® was used for the Office 365 tenant-to-tenant migration, including email, OneDrive and Teams.

The Results

Using these tools, the IT Naturally team were able to keep the customer’s primary mail domain available throughout the migration weekend, and even able to have users send mail from their normal email address regardless of whether they’d already been migrated or not.

Everything was completed over the weekend, starting on the Friday evening and finishing Sunday night, albeit with some very long hours worked!
