Good question. This is neither obvious or straightforward with CVS. It also requires administrator priviledge.

To move a file and save it's revision history, do the following:

• In the repository copy the file to the new name or location.
• Then in a working copy of the repository, move to the directory where the original file exists, then execute these commands to actually remove the original file:

  rm oldfile
  cvs remove oldfile
  cvs commit -m "moved to newfile" oldfile
