git push newremote refs/remotes/oldremote/*:refs/heads/*

This command will push all branches from the oldremote to the newremote. The refs/remotes/oldremote/* part specifies that we want to push all branches from the oldremote, and the refs/heads/* part specifies that we want to push them to the newremote as branches.

For tags, that would not be so much complex, just git push newremote --tags would be enough.

Recently I needed to work on the upgrade and migration of a project that was using Mediasoup… version 1.2.8, published 8 years ago and totally outdated up to the point that the documentation for that version was removed from the Mediasoup website:

mediasoup v1 is no longer documented. Sorry. Anyway it’s no longer maintained so please move to the latest version.
