Usage (must have MKS open):

Make a new folder... then...

git init
./mks_git_checkpoints.py <MKS project path> | git fast-import

  2. Only works on baselined versions right now.

You can connect to MKS using "si connect --gui" to "handle credentials".

Hi @kwharrigan,
do you know if there exists any tool to move source code from MKS to GIT or are your script here the only option? We want to move 20 MKS projects to GIT and would like to use some tool for this.

@XenulsWatching :- When i run your script, i keep getting this error :-
File "mks_checkpoints_to_git.py", line 18

SyntaxError: invalid syntax
