Can I migrate mailboxes from Office 365 tenant to another Office 365 tenant?
How can I migrate users mailbox from Office 365 tenant to Office 365 tenant, I have found Microsoft blog https://docs.microsoft.com/en-us/exchange/mailbox-migration/migrate-mailboxes-across-tenants to complete the migration process with this way I need third party software.
Due to the urgent need, I have to migrate users data from one Office 365 tenant to parent company Office 365 tenant, so suggest me a solution to perform this migration task.
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.

We ran a similar tenant-to-tenant project on the EdbMails Office 365 Migration Tool and moved mailboxes, contacts, calendars, and OneDrive across with the folder hierarchy and permissions still intact.
It actually priced lower than BitTitan but still covers the full Microsoft tenant-to-tenant set: mailboxes, public folders, shared mailboxes, archive mailboxes everything. The bulk license also worked out less than the per-mailbox pricing we'd seen elsewhere. What really helped was the delta sync. We ran a full initial pass before cutover, then on migration day just pushed the changes, so downtime came out to zero.
On the support side, we had questions during the migration and got responses quickly each time. Security-wise, it uses OAuth 2.0 for authentication and TLS encryption for data in transit, and it's ISO 27001, GDPR, and SOC 2 compliant. Worth getting a quote or trial run with your actual account count and data volume first.Hope that helps.
- Would recommend BitTitan for this one
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.

Best, ChrisChrisHoardMVP 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

Agree with Linus! Use a third party tool! I've got some experience with some tools so let me know if you need tips on which one to use!!

Thanks for your suggestion: LinusCansby Yes, this task is possible with third party software, I have used SysTools Migrator for Office 365 to Office 365 migration and yes with this tool I have successfully migrated my data.
