New environment, now AOS?

Hi everyone

Currently, I have two environments: one test and the production environment. Both run on their own hardware and use a dedicated AOS instance. Now I need a second test environment for things like patch testing and migration testing. The question is whether I can install a second, separate database under the same AOS server I use for test to achieve this goal. Or will I need to install a third AOS instance?

If it is possible, is there a guide or instructions somewhere on how to do it? Thank you for your time!

Yours
