There are two Performance Management environments that are both production.
One is the primary environment managing the company as a whole.
The other is a smaller legacy environment managing just the corporate side of the environment.
The work the smaller environment is doing has been moved to the larger environment in order to decommission the smaller legacy environment.
A full migration is not possible.
Can the Scheduled Reports be migrated from one system to another?
All supported Performance Management releases
Normally scheduled reports are migrated via database save and load cycles when performing a standard migration.
There is no way to export the scheduled reports from one system to another.
To have a feature like that developed and added to the product requires an Enhancement Request. These can be submitted via the Ideation page found in the Broadcom Communities site here.
