After file store move, RGS not working

Hey all

At a customer I had to move the Skype for Business File Store from a Enterprise Pool to a new Location. I used the MS Docs: https://docs.microsoft.com/en-us/skypeforbusiness/manage/topology/move-file-store-data

Almost all went well, but after removing the old Share, the RGS won't work anymore. In the eventlog the following error is showing:

Event ID: 31192

Source: LS Response Group Service

General: Workflow has setting that are not valid.
The workflow "xx" with GUID "xxx" has settings that are not valid and will be terminated: File "\\old_share\....." not found.

Why the RGS still search on the old Share? When I create a new RGS the same happend. The file will saved in the new File Share, but the Event is showing, that the file is not found in the old Location. What I missed? Where can I configure the Path of the Files?

Regards
