Can I migrate mailboxes from Office 365 tenant to another Office 365 tenant?
Hi,
Yes, use a a third-party tool. It is the fastest and easiest way for you to migrate mailboxes between two tenants. If you are changing domain at the same time these tools can help you rewriting addresses in your mail objects. Some tools also help you to create the new users in the new tenant and assign licenses.
You could export mails to PST and import them but will take you a while and will be more complex so the time you have to put on it will be more expensive than the license cost for the third party tool.
Have done several tenant to tenant migrations with this, it covers Exchange and OneDrive. Would also recommend ShareGate for the SharePoint work. If you are using Office this can simply be disconnected and reconnected if you are moving over to the same SKU in the destination tenant.
Just to note (or a caveat), that tenant to tenant migrations are more complex if you are already using multiple workloads. If you just have Exchange and Office, for example, it is reasonably straightforward. If you have, for example, Flow then you will have to completely rebuild them as there is no migration tool. It may also involve the manual move of data if you are using Stream because again, there is no migration tool.
Hope that adds to the conversation.

ChrisHoardMVP using a third party tool can we migrate Policies as well? i know we can't migrate policies migrating a data from file server to sahrepoint online or exchange server to office 365, is it the same case for tenant to tenant migration?
- Hi santhumax
It would depend on the provider and their tool. I would reach out to the third parties and inquire if they cover what you are specifically looking to migrate. You will also have to balance functionality with the cost of that tool.
Hope that helps
