It disturbs me you received no answer on this forum. I'll leave something for others who still have this question.
We use the Oracle adapters (not SAP) but ERP adapters are platform independent. You may have a component that installs on your unix SAS platform different than on Windows; however, you license to the SAS adapter doesn't change.
If you were using Windows command line processes as well since your platform was on Windows but will now be on Unix, you may have to get the SSH adapter for unix/linux so that you can invoke OS level processes in the new SAS environment. But you business processes scheduled under the SAS adapter should work as is (or by increasing the patch level of them). Typically going from Windows to unix you're likely updating your SAS version so you need to check that version support with Tidal.
SAS platform are a good time to get your Tidal SAS agent up to the latest patch level as well.
