Experience exporting source code from p4 to p4 using vcp?

Hi,

We have a need to export a few codelines from our p4 repository to
another p4 repository.  This will allow us to run the separated code in
its own p4 port.  

Has anyone experienced this type of exporting using vcp?  Did you
encounter any issues during the export?  Can you selectively export
certain changes of code from the codeline or do you have to export the
entire codeline from beginning to end?

P4 Server version: P4D/SOLARIS26SPARC/2003.1/48448 (2003/09/12)
