[p4] Branch Names

[Vineet Venugopal]

Hi ,
 
A simple question 
 
1. Can the perforce - rename strategy as mentioned in the cmd ref guide be used to rename a branch from say oldbranch to newbranch?
 
2. Also once the branch is renamed to newbranch can I recreate oldbranch using a totally different branch spec?
 
Coming from a clearcase background , I was able to do these operations easily, so if these are operations that are shunned by the perforce world , please let me know.
 
Thanks
