What happened: after the downgrade from 8.4.5 to 7.5.1 not able to load predefined datasources and queries in panel. In the panel, the data source dropdown shows option not found, even the datasource existed.
What you expected to happen: Even after downgrade we should be able to bring up dashboard with previous datasources and queries.
How to reproduce it (as minimally and precisely as possible):
- Install grafana enterprise 8.4.5 image using docker, draw a line chart with InfluxDB datasource
- rollback from enterprise 8.4.5 to enterprise 7.5.1
- Try to open up the dashboard
