How to upgrade from Squidex 5.9.0 to 7.8.2

I did the same upgrade three days ago. If I send 5-6 request at the same second for example “api/content/app/schema/?ids=x”,
“api/content/app/schema/?ids=y”,
“api/content/app/schema/?ids=z”…
I’m getting one of them, a 408 error.

This has nothing to do with the migration.

408 usually means timeout. So there are 3+ potential culprits:

  1. Your reverse proxy.
  2. Squidex
  3. MongoDB

The first goal is to check all logs.
Then you should get an idea about performance. Use monitoring or open telemetry to see the performance details. You can also enable mongo profiler to find slow queries.
