Sharing pool object between orm and existing code that use pool directly

We have existing code that basically use the following pool object from mysql:

var mysql = require('mysql');   
var pool = mysql.createPool(connectionParams);
pool.query(...);

And we added orm to the same project:

app.use(orm.express(myConfig, {
    define: function(db, models, next) {
    db.settings.set('query.debug', true);
        models.User = new User(db);
        next();
    }
}));

I'm to find a solution to share the mysql connection without migrating all existing code over. Is there a way that I can either:

1. Get the pool object from the orm db object (I can't seem to find it), or

2. create a pool object from the orm db object to share the same connection?

Thanks in advance!
