Proxmox 8.4 VE upgrade matter.

I'm just starting out my adventure with Proxmox VE, so I have two questions.

1. Since I have PVE 8.4 installed and literally two simple Debian virtual machines running on it, is it worth upgrading from PVE 8.4 to 9.0 as instructed, or is it better to do a clean install of 9.0? I'll add that it's easy to install or restore my two simple virtual machines from a backup. Even if I lose them, it won't be a huge loss.
2. If I have a support subscription number purchased for version 8.4, will the subscription still work after a clean install of 9.0?

Best regards

1. It's up to you. Either follow the upgrade guide carefully or install fresh and do all setups and tweaks again. 2. Yes, it's not dependent on the version.
