Merge Office 365 tennants?

[davyboi]

Hello

 

I was Wondering if it is possible to merge two existing schools Office 365 tennants into one? so all the accounts, email addresses, , mailboxes, other data remain the same but are all together under one account?

 

For example,

 

SchoolA use Office365 SchoolA.org

 

SchoolB also use Office365 SchoolB.org

 

SchoolA and SchoolB come together and join an academy trust.

 

Can A and B be joined so that there is only one admin console to manage, and to make it easier to setup distribution lists and shared calendars. But also keep their email domain separate (so that when creating a new account I can choose SchoolA or schoolB from the dropdown)

 

Hope that ramble makes some sense!

I am doing this at the moment. But with only mailboxes.

 

I am using IMAP migration to move mail, then doing a PST import and export for calendar and contacts. This can be done using the ediscovery and this tool - https://support.office.com/en-gb/article/Use-network-upload-to-import-PST-files-to-Office-365-103f940c-0468-4e1a-b527-cc8ad13a5ea6
