Migrate from Perforce to Git

I had been using Perforce for revision control mostly for Windows and binary files (excel, PDF, etc.). It worked amazingly well and had a powerful GUI! However I finally decided to consolidate on Git.

Primary instructions are from git scm

In CentOS you will need the helper package:

$ sudo yum install git-p4

The following steps worked perfectly for me.

  • My Git projects are in ~/git (where the converted project will end up)
  • My Perforce server is on atlas
  • I use ~/work as my working directory (where I clone, checkout, etc.)


[mirandam@atlas ~]$ mkdir ~/git/p4proj
[mirandam@atlas ~]$ cd ~/git/p4proj

[mirandam@atlas p4proj]$ git init --bare
[mirandam@atlas p4proj]$ cd ~/work

[mirandam@atlas work]$ export P4PORT=atlas:1666
[mirandam@atlas work]$ p4 login
Enter password:
User mirandam logged in.

[mirandam@atlas work]$ git p4 clone //depot@all p4proj
Importing from //depot@all into p4proj
Reinitialized existing Git repository in /home/mirandam/work/p4proj/.git/
Import destination: refs/remotes/p4/master
Importing revision 189 (100%)

[mirandam@atlas work]$ cd p4proj

[mirandam@atlas p4proj]$ git remote add origin ~/git/p4proj
[mirandam@atlas p4proj]$ git push origin master

Now in my work directory I can perform changes and continue working.
