Answer by elliot for Git push existing repo to a new and different remote repo server?

The way I've accomplished this is:

1. Create a new repo on github (new-repo.git)
2. cd old-repo/ on local machine and fetch all new changes
3. git push -u https://github.com/[username]/new-repo.git main -f
4. Clone your new remote repo https://github.com/[username]/new-repo.git to your local environment

I've found this a simple way to essentially copy an old remote repo into a new remote repo.
