Your problem is that you want to modify a table with existing constraint. I see two solutions:

If you are in dev, you can rebuild your database

doctrine:database:drop --force
doctrine:database:create
doctrine:schema:create

If you're in production it's a little more complicated.

One solution I see is that you could create a command to save your data, delete the data in the tables you want to alter, modify your schema, reload the data once your table is altered. Depending on the changes, it shouldn't take more then 2-3 hours. Just make sure you have a backup in case your command goes south.
