Hi,
Let me explain my problem.
My challenge (in fact, thanks to my client...) is to create a
application based on symfony.
It has multiple databases. One master, for the application, and
others, for reference tables.
I know that in symfony, I can enumerate multiple databases in the
databases.yml.
In your case it's a good to use web services to abstract database
model B as you know it'll be modified soon.
Where I disagree is putting all on the same SF project, you should
separate your app in 2 parts :
- The main project, embedding A database models and acting as web
service consumer
