When trying to add a Data Aggregator Data Source to Performance Management getting an error:
"Adding Data Source failed. Data source is already registered to another Performance Center"

Note that if the NetOps Portal was reinstalled without any backup loaded from the old system, many things will be missing and require recreation. The most often used examples of things needing rebuild will be Users/Roles, Groups, custom Reports (Dashboards, Context Pages, On-Demand Reports), Scheduled Reports, etc.
