Moving to new domain - advice please.
In parallel with my other thread today regarding export - import of Exchange data.
I want to make sure that I have all i's dotted and t's crossed before we hit the go button next Monday.
We're migrating everyone and everything to a new domain as follows:
SBS2003 - apart from it's DC and Exchange duties it runs WSUS and that's it
1 x Member Server 2008 box running SIMS & Sophos & some file storage. Also acts as a secondary DC
1 x NAS box running Storage Server 2003 - file server. This holds all the users home folders and other data, nothing is stored on local PCs.
1 x Server 2003 print server
~100 client PCs - mainly W7 with a few legacy XP machines
85 users with mailboxes
MOVING TO THIS SCENARIO
1 x Brand New Server 2008 R2 Ent DC
1 x Brand New Server 2008 R2 Ent running Exchange 2010 Ent
The 2008 and 2 x 2003 servers in the current scenario.
All user accounts have been created on the new DC and mailboxes created on the Exchange Server with same names and logins as originally used.
So my plan is to export the Exchange data with Exmerge onto the NAS box, demote the Secondary DC and remove all servers and PCs from the current domain into a workgroup.
Add all machines into new domain.
Import old Exchange data into new 2010 server.
It all *seems* relatively straightforward, however, one of my concerns is data ownership. How can I ensure that the users will be able to access their data? Ownership will have been conferred under the old domain and the SIDs will be different for the newly created users, presumably I will need to transfer ownership of the files to the "new" users but how can I best achieve this?
Do I need to take local admin ownership of the server data once the servers are unjoined from the old domain, or do I need to take local admin ownership of the client PC C-drives, or both? How would I achieve this?
Apart from the Exchange export and import, data ownership is my biggest concern; I don't want to set everything back up only to find that users can't access their data.
Advice would be most welcome at this chewing-fingernails stage please :)
