Migration exchange 2007 to Office 365

[Fouad Bouharrada]

Hello,
I would like help to migrate from an Exchange 2007 solution to an Office 365 version. We have about 150 mailboxes.

Regards,
Fouad

I recommend you to check the Exchange Deployment Assistant to get all the information you need for your migrations scenario: https://docs.microsoft.com/en-us/exchange/exchange-deployment-assistant

You can also look into one of the various 3rd-Party migration services, especially if you need to co-ordinate the move with other systems like e-mail archiving systems
