z/OS compatability with ADABAS V8.2.5 and Natural V8.2.3

Hello,

We currently have z/OS 1.13 with ADABAS V8.2.5 and Natural V8.2.3.

We are working on upgrading the z/OS to 2.2 and would like to know if they are compatible under it, or do we necessarily need to upgrade to a newer version prior it?

We are aware that these versions are out of support and would very much appreciate every answer available.
