Hi.

Accidentally upgraded PMM2 server version from **2.28.0 to 2.32.0** and we have errors like this on many graphs

```auto
Error message

server error: 500: <html>
<head><title>500 Internal Server Error</title></head>
<body>
<center><h1>500 Internal Server Error</h1></center>
<hr><center>nginx</center>
</body>
</html>

```

Is there any way to downgrade the server version back to 2.28.0 without re-installing it ? we need the previous data to be available.

Thanks in advantage !

Hi @Ani_Ghoghoberidze sorry for the delay in responding - do you still see this issue? usually this `nginx` error is resolved by restarting the container.

Failing that, can you navigate to the PMM settings dashboard and download the `logs.zip` so we can examine the errors in detail?

Downgrading is supported only by restoring from backup. do you have a backup taken from 2.28 we can use as a restoration point?
