Upgrade Clustered File server from 2003 to 2008 R2 - Rename Cluster?

We currently have a 2-node File Server Cluster running Server 2003 using direct attached storage.  Our existing cluster name is File.  We plan on upgrading our existing cluster to 2008 R2 by using the procedure outlined here.

My concern is that you cannot have two clusters with the same name.  Therefore, our new cluster name would be created as File2.  After destroying File, can we change File2 back to File?  This would allow us to keep all our resources/group policies the same for all the file shares.  I cannot find any good microsoft articles that say you can change your Cluster name.  My other thought was to create a static DNS entry to point File to File2's IP.  

Suggestions?

Renaming the 2008 file server cluster virtual (CAP) name from File2 to back File there should be no issue.

One will have to delete and recreate the VCO/CNO in AD for the 2008 server and there verify DNS is happy with the host name to IP changes.

2008 cluster VCO\CNO info:

65td,
Thank you for responding.  I have created a 2-node clustered file server test environment.  I am not used to having a separate CAP and VCO/CNO.  I guess I was used to Server 2003 Clustering.  Nevertheless, I changed both CAP and VCO without issues.  I figured I would not need to change the VCO/CNO.  I will only need to change the CAP.  I could care less the cluster name, I just want to make sure all my file shares will continue to work.  Thank you for your help.
