Hi All,
I was wondering if anyone would know what the best plan would be to migrate one domain with Office365 to another that already has Office365?
We have an acquisition who already has Office365 and was looking to migrate their mailboxes into our O365 tenant.
Hey @Waqkas-Ahmed ,
This article explains how to migrate mailboxes and service settings from one Office 365 tenant to another Office 365 tenant in a business-merger scenario.

@Mike-Rodrick I've gone through the article, however is there any more info on how it works and the work/planning required to migrate one domain to another?
You must detach the acquired accounts from the original domain before adding it to the new domain. This may disrupt the flow of email several times in the progress
If changing usernames too, a mailbox identity can be changed and requires a reconfiguration of each outlook client.
Passwords will not be migrated. If using AD Connect (DirSync), any changes will require credentials be upgraded too.
This is not an easy process. There are 3rd party tools that you can pay for to make it a little easier.
This link gives you a picture of what you might need to consider before tackling this on your own: https://www.freeviewer.org/blog/combine-two-office-365-tenants/
