Question

I want to set the start value for auto increment on a column to 1000000 (to avoid conflicts with a legacy application), but can’t find any documentation that tells me how.

Pretty standard table, here’s what the relevant bit looks like:

User:   
  attributes:
    export: tables
  columns: 
    id:
     type: integer
     primary: true
     autoincrement: true
    code:
     type: string(6)
...

The best way to acomplish this would be the creation of a Doctrine Migration. There you are able to set the value of the sequence table to the value you want. Migrations are easy to use (http://www.doctrine-project.org/projects/orm/1.2/docs/manual/migrations/en#migrations) and you can run it during your deployment process of your application.
