Windows Fileserver Migration

Hi all,

I have a cluster of 2 Windows 2003 Enterprise Servers connected to a SAN. They are both DCs but essentially all the setup is doing is mass file storage currently. The warranty on the kit has just run out and the renewal cost is ridiculous.

So I am replacing the lot with a single decent spec 2008 Enterprise machine with a RAID 10 array.

Currently the main file share which all clients talk to has a one name let's call it \\OLDFILEAREA and the 2 servers are say \\CLUSTER1 and \\CLUSTER2. The new server has a brand new name say \\NEWSERVER

In terms of moving all the data I intend to use Robocopy to retain all the permissions.

The bit I'm worried about is the fact that I want to create a share on \\NEWSERVER which has the same name and appears identically to \\OLDFILEAREA ie you go Start/Run \\OLDFILEAREA and see just what you see now on the old setup. I don't want the new server name to appear in the share name.

I assume I can do this using the local DNS, but have never done it this way before. I'd greatly appreciate any comments or advice on how I can go about doing this without big headaches!

Cheers,

Create a DNS alias to point the old names to the new name, remembering to disable strict name checking

Simple

Thanks for that mate, very helpful. So I can create a DNS alias for \\OLDFILEAREA which points to \\NEWSERVER\NEWSHARE and not just to \\NEWSERVER?

Use a dfs name space?

Have you done similar this way? I'm not familiar with dfs shares.

Very helpful, many thanks. Yes the old server will be shutdown first.

In terms of the strict name checking. Should this be set on the new server itself, or on the DNS servers?

On the new server - basically, by default it will only respond to requests for it's own name (hence strict name checking). So you would find \\newserver would function perfectly but \\oldserver wouldnt, despite a ping to oldserver returning packets from newserver

Legend. Thanks very much!

That's fair enough, i only said it because you mentioned they were DCs and doing a data migration then demoting and decomissioning a couple of DCs isn't always that quick a process. So chances are you will want the new share working before the old servers are fully down. If you don't remove the name it will keep trying to register in DNS.

Yeah very valid point. Thanks mate!
