@Ricardo at the official documentation theres a section explaining context management (i.e switching databases using the same document: http://mongoengine-odm.readthedocs.org/en/latest/guide/connecting.html#context-managers). The following code will switch the class User, originally stored in users-db to the new database archive-user-db

from mongoengine.context_managers import switch_db

class User(Document):
     name = StringField()

     meta = {"db_alias": "user-db"}

with switch_db(User, 'archive-user-db') as User:
     User(name="Ross").save()  # Saves the 'archive-user-db'
