Perforce: How to Integrate Upto a Certain Changelist From One Branch to Other

Question

I am trying to take all our recent code from our development branch to release branch upto a certain changelist (say CL no. 1234). How can I achieve that?

I know that I can do p4 describe 1234 to see the timestamp and then do p4 integ //path/to/dev/branch/...@timestamp //path/to/release/branch/.... But is there a more elegant way of doing this?

Answer 1

Integrate your dev branch (source) into your release branch (target) at a changelist, rather than integrating using a timestamp. Since you want to integrate up through CL 1234, you should run the following command:

p4 integrate //path/to/dev/branch/...@1234 //path/to/release/branch/...

This integrates the dev branch (all files in the state they were in after CL 1234 was submitted) into the release branch.
