You can skip the minor upgrades, minor being the number to the right of the decimal point.

Subject: [support] Upgrade from 7.16 to 7.22
 

Hi to all,
I have website with Drupal 7.16 on it. Plan to upgrade to the latest version, 7.22.

Is it safe to upgrade directly from 16 to 22 or I have to go version by version, or something?

Thanks.
