NAME:
P4Transfer.py
DESCRIPTION:
This python script (2.7/3.6+ compatible) will transfer Perforce changelists with all contents
between independent servers when no remote depots are possible, and P4 DVCS commands
(such as p4 clone/fetch/zip/unzip) are not an option.
This script transfers changes in one direction - from a source server to a target server.
Usage:
python3 P4Transfer.py -h
The script requires a config file, by default transfer.yaml,
that provides the Perforce connection information for both servers.
An initial example can be generated, e.g.
P4Transfer.py --sample-config > transfer.yaml
For full documentation/usage, see project doc:

# Once you have set this value and started a transfer DO NOT MODIFY IT or you will potentially
# mess up integration history etc!!!!!
# IMPORTANT NOTE: setting this value causes extra work to be done for every integration to adjust
