No data after upgrade Grafana

After I upgraded from 12.2.2 to 12.3.0 I experienced similar problems. Opening the browser dev tools showed many console errors about loading all plugins. The URL for each plugin was incorrect compared to the app folder structure. I also noticed the missing icons which I see in the second screen cap.

what approach did you use to upgrade

what os are you on? is it docker?

Windows binaries copied to a new folder, changed the path in the Windows service settings, recycled. The same way every release since 8.x (I really need to delete some old versions). I reverted the path change when it wasn’t right and I didn’t keep a screen capture, sorry.

The path in the dev tools console to the plugins seemed to be missing the folder name of the plugin before a “.js” file name (e.g., “…/grafana-lokiexplore-app.js” or something like that). Now that I look at the plugin folder structure I would guess the folder name was prepended to “module.js” as the file name.

this is what I do (upgrade one full version at a time. not like 8.x to 12.x. Only 8 to 9 , 9 to 10 etc)

  1. Download grafana zip file and unzip
  2. from old grafana folder I copy data and conf folders over to new grafana folder
  3. manually run `grafana-server.exe` from bin folder and see what happens.

My data and config live outside the binaries folder.

upgrad to 12.2.1 version i will work fine.
