We are upgrading SRM from EhP1 to EhP2. In a classic scenario, we are integrated with our core ERP system.
The initial landscape build looks like:
Break/Fix line: SRM 7.01 DEV --> SRM 7.01 QA --> SRM 7.01 PROD (current)
Upgrade line: SRM 7.02 DEV --> SRM 7.02 QA --> SRM 7.02 PROD (upgraded)
Our core ERP line is/will be integrated with the upgrade line. The concern is for break fix/maintenance issues we need to perform in the BreakFix line, what's the best way to address the lack of a separate ERP line for DEV and QA?
