exchange online migration
So have Two office 365 tenants - that have to migrate, so it ends up in already existance of company-b.com
Company/tenant = company-a.com
Company/tenant = company-b.com
So all company-a mailboxes must be migrated to company-b. What is the best way to archive that ?
With the build in migration tool in exchange online or some third party tools. There are only about 5-10 users so not many.
Overall requirement is also that if any send mail to company-a.com it should still end up in the migrated mailbox of company-b.com, so mails are not lost, if any use the old domain name

- For that many users, manual export/import will be the cheapest, and probably the fastest option.
For 5–10 users, manual export/import might seem cheap, but in my experience it’s time-consuming, risks losing data, and doesn’t preserve folder hierarchy well. I used EdbMails Office 365 Migration instead — it was cost-effective, preserved all mailbox folders and items, and even handled incremental updates for any new emails during the migration, making the whole process much smoother.
