Cross tenant Microsoft 365 groups migration without data loss

Hi All,

As part of my Cross Tenant migration / Consolidation project, I need some help and suggestion on how to perform the migration of Microsoft 365 groups to another Office 365 tenant without data loss.

So far I can only see this article which requires me to buy 3rd party software: https://docs.microsoft.com/en-us/exchange/mailbox-migration/migrate-mailboxes-across-tenants#scenario-migrate-using-a-third-party-migration-tool

What's the built-in method or the procedures from Microsoft without additional purchase?

Thank you in advance.

Microsoft doesn't offer anything in this space. Either go for a third-party tool, or be prepared to spend lot of time/effort for manual migration tasks.

@EnterpriseArchitect,

It has no official tool to realize Microsoft 365 tenant-to-tenant migrations now. The following image shows the migration details for each product:

Besides, here is an article which contains the tenant-to-tenant migration architecture model in PDF for reference.
