Hi All

I'm currently upgrading to episerver 9 using automatica database schema - it all works like a charm in dev machines . However it is failing on larger database size (copy of prod) while upgrading db schema with the following error

Any ideas before I take the manual db update route?

My best guess is that it's waiting for an update to complete but times out...

Might work to just hit it a few times :)

I would dotPeek that method and see if I could increase timeout. If that doesn't work, so each step manually I guess.

There is a 5 minute command timeout in GetDatabaseVersion. In this method it only gets the current schema version but failing at that step with exception -2 which is command timeout.
