Changing Server Question

[WALTERS, CRAIG P [AG/1000]]

We are moving our CVS repository to a different machine soon.  We currently use 
the actual machine name that holds our repository in the CVSROOT so any 
projects that are checked-out have this machine name in the CVS\root file.  

We have more than 100 projects using CVS.  Do we have to have everyone commit 
all changes before we move the repository to the new machine and have them do a 
fresh checkout or can we just write a script to update all for the CVS\root 
files to use the new alias?  Or better yet, is there something in CVS or WinCVS 
to do this?

Thanks IA
