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.
