The document with Microsoft’s method for migrating SBS 2003 to the new SBS 2011 Essentials product can be found here:
Note that the SBS 2011 Essentials Web site’s section on migration is a bit buried.
We then end up at this page:
- SBS 2011 Essentials: Migrating Windows Small Business Server 2003 to Windows Small Business Server 2011 Essentials
The migration process itself looks to be quite a bit different than it is for migrating SBS 2003 to SBS 2008/2011. The requirements for a healthy source server network still stand along with the prerequisite of an up to date source server.
We will be doing a couple of dry runs through the process with a client’s SBS 2003 R2 Premium OS image to make sure that we don’t run into any real problems.
Since the number one hang-up in our own SBS 2003 to SBS 2008/2011 migrations tend to be Public Folder related we are hoping that we will not run into too much difficulty!
