Is your migration team still waiting on the identity team to finish tenant setup before they can start migration batch configuration?

I assisted in creating over 200 Security Groups in the new subdomains as part of acquisition migration prep. Security Groups aren’t a migration cleanup task. They’re a cutover dependency that blocks SharePoint permissions, Teams membership, and M365 license group assignments from working on day one.

The sequencing: Security Groups in the target tenant need to exist before you configure your MigrationWiz user mapping, before you set ShareGate destination permissions, and before your test accounts can validate that migrated content lands with the right access.

I also hold the MCSE: Productivity and Microsoft 365 Certified: Fundamentals credentials alongside AZ-104 and AZ-305, which cover M365 tenant architecture in depth. The practical application is this: tenant configuration isn’t IT infrastructure work. It’s migration work.

Where in your migration timeline are Security Groups and tenant prep getting completed relative to tool configuration?
