how far can I upgrade plesk?

[daffoml]

I've inherited a server running 7.5.4, and the updater lists every version between, i.e.:

Plesk 7.5.4
Plesk 8.0.0
Plesk 8.0.1
Plesk 8.1.0
Plesk 8.1.1
Plesk 8.2.0
Plesk 8.2.1

Can I just jump up to 8.2.1, before moving up to 8.3 (which I assume will show up when I get to 8.1), or do I need to upgrade incrementally?

Thanks

Mike
