We have the basic steps outlined for the migration process from SBS 2003 through to SBS 2011. We have not had time to get them together in a blog post yet.
But, we are just about to run through a migration virtually prior to running the actual migration for a client so we will validate all of our steps then.
Once we are confident that our steps follow the Microsoft documentation and also include the extras that we see as part of the process we will be releasing our migration guide.
We are also getting ready to migrate an SBS 2003 R2 Premium site to SBS 2011 Essentials as their e-mail resides on a hosted Exchange server setup. So, we will be running through the Microsoft documentation and creating a guide for this process too.
More to come and thanks for reading! :)
