Currently we are planning to migrate the all the print queues from one print server (A) to another Print server (B). these are domain members and both are Windows Server 2008R2 Standard Sp1.

Print Queues:

All these Print queues are Listed in AD, user used to connect them by browsing the Active directory.

Now, we are migrating the all the print queues with to another Print server name (B). But dont want any action end user.

The below propose action will help in this case or not.

By creating the cname record (A) to pointing older server name to new server (B) will fix the

The main issue I see is that the printers will be published using machine name B.  New connections will be created with the new name.   If you are taking machine A off the network and the DC are configured to prune print queue objects, the objects will be removed about 8 hours after the machine is off the network.  I have a feeling this is not what you want.

For existing connections make sure you follow the guidelines for using CNAMES with Server 2008R2 machines with shared printers.
