Renaming branch?

[Alain Novak]

Hello,

In CVC documentation I found out, that it is possible to rename tags. 
But I would like to rename branch. 
Is it possible at all? And if it is possible, how to do it? 
One possible solution could be to search for branch name in whole 
repository and then change branch name in every file where it is 
mentioned. Is this possible to do without damaging the repository?

Best regards,
Alain
