I want to know how I can migrate the Exchange Online Mailboxes and it’s contents for all the users on an Office 365 Tenant to another O365 fresh Tenant?
Also, is there any 3rd party tool that i can use to achieve this?
Does Sharegate provide the option of migrating mail boxes too for multiple users?
How can it be done without using any 3rd party tool?
Well, I always prefer following Exchange server deployment assistant guide which is available from Microsoft team.
It asks few questions about your current environment and further, provides step by step details by checking all necessary prerequisites.
