We are migrating data from one server to another.  All users have a mapped drive to the old machine.  How can we point requests for that old machine to the new one?

Example  --

User has Server A mapped as a drive.   Migration happens.  User needs to point to Server B now for the mapped drive.  How can we forward all Server A requests to Server B?

It depends how has you configured access to shared folders. You may use GPO. In case of script, you can configure it in such a way, that the script test whach server is accessible.

Another path is via DFS. Check Technet documentation.

Hi Dizzelk,

As Milos mentioned, we may use Group Policy to achieve the goal.

Here is the reference for Group Policy:

Here is the forum for Group Policy:

In DNS, if you want clients to get the IP address of Server B when querying for Server A. We may change the IP address of the Host record for Server A, or delete the Host record for Server A and create an Alias pointing to Server B.

Here is the guide:

DFS is definitely the way to go.
