I actually just did this exact move last month but I stopped at 12.1.7-h3, I think you can do larger jumps if you're not using an HA pair, but these are the steps for an HA pair:

 

Download 11.0.0
Download/Install 11.0.4-h6

Download 11.1.0
Download/Install 11.1.13-h9

Download 11.2.0
Download/Install 11.2.10-h3

Download 12.1.2
Download/Install 12.1.7-h3

 

I think 12.2.2 is considered a base, so you can just download that and install afterwards.

 

Talking to Support previously for standalone they said you can go from 10.2 -> 11.2 -> 12.1 if you're using a standalone firewall.
