Well, too soon to say boodbye. Thought I used --change-db-credentials in the restore, the engine seem=
s
to be unable to connect to the database. I assume that it didn't get t= he new password, so, is there a way to tell the engine about the new pass= word? Regards, /etc/ovirt-engine/engine.conf/10-setup-database.conf or similar. Look for ENGINE_DB_* variables.

Hi Yedidyah,
But If I run engine-setup and then engine-backup restore shuldn't it=
import the data to the existing db created by engine-setup? That's shown everywhere so I thought it's a valid way to migrate No.
There is a specific case in which this works automatically: All on the same host: 1. engine-setup 2. engine-backup --mode=3Dbackup (perhaps do other stuff here) 3. engine-cleanup 4. engine-backup --mode=3Drestore
Why does this work? Because 'engine-cleanup', since 3.3, does not dro= p the database nor user inside postgres. So when restore tries to acces= s this database using this user and password it succeeds.
In general, if you do the restore on another machine, and do there 'engine-setup; engine-cleanup' as a quick-postgres-provisioning-tool,=
you end up almost ready, but not quite - because the password is rand= om, and therefore different between the installations. In principle you c= ould have provided just the password to restore, but we decided that if yo= u need to change the credentials, you should pass all of them (except f= or defaults).
Hope this clarifies,
