We are on 7.1.8 pega version. Trying to install DevOps acceleration pack but not able to find DevOpsAccl_Server<XX>.zip in 7.1.x pack. Please help me on how the whole things will be tested without 7.1.x DevOpsAccl_Server<XX>.zip
DevOps Acclerator Pack is a client-server model. For that client can be on any Pega 7.1.5 and above version. But server(DevOps Server Pack 7.2) should be on Pega 7.2 and above version. To get the DevOpsAccl_Server<XX>.zip, download the 7.2 pack. For more info you can read the Installation Doc inside downloaded build.
As I mentioned in the previous comment for DevOps Server Pega 7.2 or above version is mandatory. So for POC purpose you can try with Personal Edition of 7.2. Even we have not tested with Personal Edition. But its recommended to use Professional Edition only(Because Pega will not give any support for Personal Edition for Product bugs).
