I did a migration from an ubuntu linux box to an OSX machine. Everything is fine except the filestore attachments. Unfortunately Odoo is trying to get the attachment with a different id on the target server. Is there any magic stuff with sha1 to configure to get the same id on both servers.

2017-09-21 17:30:45,663 2577 INFO odoo odoo.addons.base.ir.ir_attachment: _read_file reading

Thanks for your help
