[p4] script to transfer revisions and history

There is a script called perfmerge.pl (available from support) which will
combine the metadata for two servers using their checkpoints. Note that this
involves renumbering changelists, and it also requires the filepaths in each
server to be unique.
Then as Chuck says you can copy across the depot files, merge the metadata
and restore from it (after deleting db.*). If you only want a subset of one
server then just obliterate the ones you don't want (before or after the
merge - before may be easier).
Use p4 verify liberally (before and after), take backups, and be very
careful!! It does work.
