So,

Two Odoo databases that already working on another server.

I set up the Docker and start everything. Accessing -> http://server.example.com:8069/web/database/selector <- works ok but only one DB loads and let's me work in Odoo, the other one says:

odoo Skipping database [..] as its base version is not 8.0.1.3

Both my real Odoo and the dockerized are Odoo 8, accessing using in-private/incognito does exactly the same.

Any ideas?
