Recommended practices for moving an OSS project from GitHub to GitLab

Hi.

What would be some recommended practices for moving an OSS project from GitHub to GitLab? I’m clear about the technical steps (I actually made a sucessful migration test). My concerns are more on the social side, as the project has a few stargazers and some people is actually using it. The project has no website, or twitter, or anything else than the GitHub repo and a Docker Hub repo. I could just open an issue and mention all stargazers, but that sounds pretty spammy (and I already dit it once :sweat_smile:).

Could anyone share some related experiences?

Best regards,
