Exchange 2003 Removal First, Then Install 2013? - 20.Oct.2016 8:29:30 AM

Hello All,

I performed an Exchange 2003 install in my organization many years ago. It was running fine for many years and we were happy to be in direct control of the servers. The owner of the company forced us to migrate all our mail to the cloud using a Hosted Exchange service provided by a certain company about 6 months ago.

We warned him, but he is now unhappy with the cloud service and wants us to migrate all the email back in house. We are planning on using MigrationWiz and therefore will need empty mailboxes for all users.

Is it possible to completely remove our remaining 2003 servers, remove the Exchange Organization from our Active Directory, so that Exchange 2013 or 2016 will cleanly install and correctly modify the AD schema to support itself? Or will it see remnants of 2003 and refuse? Has anyone tried this?

I'm worried our only other option is to do the double hop migration from 2003 to 2010 and then 2010 to 2013 or 2016. We are impressed with 2016 because of the high availability features.

Any help is greatly appreciated. Thanks!

I actually did this one year ago, reverting to Exchange 2010 after having previously been on Exchange 2003.

It's not so straightforward, but achievable.

I suggest you call on consultancy, or you can leave me a pm.

Regards
Soren
