You can check the Checklist for Upgrade for the particular version in the Avi techdocs: For example, The link for 'Checklist for Upgrade to 30.2.x version' is as follows : Checklist for Upgrade to 30.2.x

Scroll to the section as can be seen in the following screenshot.

In the screenshot above, the first column shows the version you want to upgrade to and the corresponding row shows the versions you can upgrade from to this particular version.
For Example: If you want to upgrade to Avi version 30.2.1 from Avi version 22.1.7, it is not supported. You can only upgrade to Avi version 30.2.1 from Avi versions 22.1.1 through 22.1.6 ( 22.1.1 -22.1.6).   
On the other hand if you want to upgrade to 30.2.3 from 22.1.7, it is possible as 30.2.3 version supports upgrade from versions 22.1.1 through 22.1.7 (22.1.1 -22.1.7) . In addition, you can upgrade to Avi version 30.2.3 from versions (20.1.1-20.1.9), (22.1.1-22.1.7), (30.1.1-30.1.2) and (30.2.1-30.2.2).
