At B2CK, we have written also a migration script [1]. It migrates by
default many modules like party, account, product, sale, purchase etc.
But with some restriction, for example it does not migrate history like
posted invoices but instead only a initial balance.
The process can not be automatized because there are many differences
between OpenERP and Tryton so choices must be made.
About the price, you can request privately a quote from B2CK [2] (we
will need the list of installed modules)
