Pointing an existing groundplex node to UAT environment

Hi,

We were trying to point an existing groundplex node to the UAT environment (https://uat.elastic.snaplogic.com) and SnapLogic customer support recommends the following steps:

  1. Uninstall RPM package in the node
  2. Download UAT RPM Package
  3. Install the RPM in the node
  4. Download and place slpropz file under /etc

Wanted to understand why we need to uninstall and reinstall the RPM package since its an overhead. Is there another way to do this?

Thanks,
VJ
