How to set up 2 connections to MySQL in ZF2 + Doctrine 2?

Question

MySQL

Hi friends!
Please tell me how to set up two database connections so that you can also update the structure of these databases from the command line.
I use this solution stackoverflow.com/questions/11291502/doctrine-2-mu...
But when running the command:

vendor/bin/doctrine-module orm:schema-tool:update --force

only one database is updated.
Why do I need this (maybe tell me another solution)?
I have a system that uses an address base (FIAS, KLADR).
In MySQL, the address database takes up a lot of space (about 30GB including indexes).
I have a database backup every day, but it probably makes no sense to backup the address database, it almost does not change.
