Migration to office 365 RRS feed

  • Question

  • First we are using exchange 2007.

    What we would like to do is migrate to office 365 and keep our existing exchange server but copy no emails up.

    We would like all users to being with empty email boxes on the cloud.

     We would like to have all users still have access to the old email server.

    Now from what I have been reading we need to do a cut over migration and not sync the email boxes. Is this the best way?

    How do we continue to have access to the old email server with the dns pointing to the online server?

  • Add an Exchange 2013 server into your organization and deploy a Hybrid Configuration.  (There's more to it than that, too.)

    I really don't understand why you want to do it your way.  It seems like a great way to confuse your users and cause all sorts of inefficiencies.

  • Thanks for the response the reason we want to keep the 2007 server is email box sizes. Some of our users have over 50 GB in email boxes. So we are just using it as a archive for the most part.

  • If you deploy an Exchange 2013 server as a hybrid server, you can create cloud-based personal online archive mailboxes that they can use to move their "archive" mail to.  Both the primary and online archive mailboxes will show up in the same Outlook profile.

  • Apart from above suggestion, I would suggest you following Exchange server deployment assistant which provides step-wise instructions with all necessary prerequisites. Please check out this link for more information : https://technet.microsoft.com/en-us/office/dn756393.aspx

    Additionally, if you wish to automate the migration process, you can try Lepide exchange migrator in order perform the migration in hassle free manner.
