Hi The javaagent is compatible with the backend for all 6.x releases, even the next 7.0.0. So, you don't need to worry about that part. SkyWalking froze the network protocol a long time ago. In 7.0.0, we just add new features to the protocol, but the old one is still working.
For backend upgrade, since 6.4.0, there is a reboot feature existing in case you are doing the upgrade but erase the whole storage, which I don't recommend.
