Push Rules - Commit message for commit old

I made a project with GitLab Self-Managed Core version and that has many commits.

Now, i upgraded to Self-Managed Starter version and i want to use “push rules - commit message” function, but when i add the regular expression for messages format, i can’t make push for the new messages with correct format (i think it’s because of the old messages don’t have the formart)

Can you help me with this?


can you please share the regex you’re using and also sample commit messages from old and new to get a better picture?
