EEM and Process Automation version compatibility

[Dave Ramsey]

Hello

I am trying to determine the compatibility between various versions of Process Automation and EEM.

We are currently running;
CA Process Automation 4.2 SP01 (Build 4.2.100 SP01)
CA Embeeded Entitlements Manager 12.51.3.14

We have a requirement to upgrade the OS on which our Process Automation software resides so I need to know;

• Which version of Process Automation is compatible with Windows Server R2 - this is answered here: https://docops.ca.com/ca-process-automation/4-3-1/en/getting-started/platform-support-and-requirements/
  However, I can't see the version that I'm currently running, only newer versions.
• Version compatibility between EEM and Process Automation.
  This link mentions EEM compatibility https://docops.ca.com/ca-process-automation/04-3-02/en/installing/prerequisites/ca-eem-prerequisites
  but references the EEM hardware requirements page which doesn't appear to have any information on this.

The way the page references versions seems to be slightly convoluted. Some versions appear in the format "04.3.02" and others as "4.2.2", so I don't understand exactly what I'm looking at version wise which might be part of the problem.

Any ideas, answers, or suggestions would be greatly appreciated. 

Many thanks
