I have an Odoo 6 database with some users in table res_users and I would like to transfer them with their current passwords to an Odoo 8 database. Creating the user with the appropriate username in the field res_user.login is no problem. In a naive attempt I tried to copy the odoo 6 res_users.password to odoo 8 res_users.password_crypt but this did not work.

Does anyone know if and how this can be done?
