What is the best practice to scale this tool for more users/testers with Exception licences?

Hi Sowmya - I think you're asking about Provar Execution licenses, which are test execution only licenses (enables remote and concurrent test executions, but not test authoring). If you are expanding the QA team, you'll want those folks to be authoring tests, so you will want to purchase Developer Licenses. But....you should reach out to your Provar Account Manager to discuss the specifics of your use case. They'll make sure you get exactly what you need to support expanding the team.
