Upgrade from 5.2.2

[Alessandro 123]

Hi to all.
I have a 5.2 production server that i would like to upgrade to the latest version.

Can I directly upgrade from the web interface ? Any additional steps? Should I upgrade to each version step-by-step or straight to the latest one ?

I have to reduce downtime as much as possible. Just one reboot would be ok.

and as a next step:

Thank you.
Is that "safe" or should I expect some issues ?

Both reboot are required or can I safely skip the first (related to 5.4 upgrade) and reboot directly after the upgrade from 5.x to 6.x ?

Another question: backups are mandatory (meaning that data loss is expected) or just as safefy ?

Backup is only for your safety, like a seat belt
