resolver as a backup tool

[mbolder]

I would like to use two mysql db´s and incorporate the resolver in order to set on as the master/source db and the other one as a backup/replica.
Read the docs and set dsn1 and dsn2 accordingly, my problem is that auto migrate only checks/creates models on dsn1, so later on in the code when data is being pulled from tables I get the error that the table does not exist on dsn2?
What did I understand wrong, Does auto migrate not check both db´s ?
