Perforce, How to integrate a change to another branch?
I have used this:
p4 integrate -c 625466 //SrcPath/...@622912,@622912 //DestPath/...
Where CL 622912 is the one we want to integrate, and CL 625466 is the new CL.
To integrate changelist 100, for example, you'd use:
p4 merge //releasebranch/...@=100 //trunk/...
p4 resolve
p4 submit
(If you have an older Perforce server you'll have to use 'integ' instead of 'merge'.)
Note that '@=100' means the same thing as '@100,100' in this context.
