Migrate Old SBS2003 Server to New 2012R2 Essentials Server

We have an old SBS2003 server not R2 and have introduced a Server 2012 R2 Essentials server as an additional Domain Controller.

I have migrated DHCP and Printers to the new server and all email is with a third party provider in a hosted Exchange cloud environment.

I now have to migrate the data, shares (with all share and security permissions) and mapped drive’s and logon scripts to the new server for a hopefully seamless transition.

I would like to know the best and cleanest way to do this with the least disruption to the end users.

We will then decommission the SBS2003 server.

I script to creation and migration of the folder structure using robocopy. That way you can use it to pre-stage data, and then as a final cutover because robocopy will only capture the differences assuming you use it this way.
robocopy sourcedir destinationdir /v /mir /z /np /r:1 /log:C:\Temp\Migration.log

I script all the permissions for the destination folder set using PowerShell.
I suggest you use the NTFSSecurity add on.

When you are finally ready for the cutover of the data access, remove the shares on the source so users are not using them.
Run the robocopy script once more to catch any diffs.
Verify shares are correct on the new server.
Change home drive attributes in ADUC for users as well as logon script drive mappings being delivered to users. Test.

Make sure you move your FSMO roles from old SBS 2003 just immediately before dcpromo down the old SBS server.
SBS has a heart attack if it does not have the PDC role and it will shut itself down in the middle of the day without it. So be sure to transfer all the FSMO roles to new server just before the decom.

Please double-check your DNS replication and verify that sites and services is setup correctly with all DCs as GC and autosite coverage enabled in default DC policy.

Felicia - Thanks for your reply.

I have already transferred all five FSMO roles to the new server sometime ago, we managed to find a way to stop the SBS from shutting down.

I have decide to use Syncovery to transfer the data across to the new server and indeed it is already done and I will run it again before changing the logon scripts and turning off the old shares - it turns out there wasn't a lot anyway.

The permissions were carried over by Syncovery and a lot of the folders and shares on the SBS server are no longer required as they are specific to SBS.

I plan to make the switch this evening and hope thing are all ok in the morning when users log back on again.

I have made a simple logon script which will delete the old drives and map the new ones and I will amend the Home folder in Active Directory for Users Folders.

It wasn't complicated as there was not much in the way of different permissions and there were only a handful of users and the data was only 5GB
