Hi All,

Was hoping someone might be able to assist. I am currently running openerp 7 and it works perfectly, I installed the trunk on a test server as I wanted to test out the new website builder. When I try to import my openerp 7 database I get the error "Uncaught TypeError: Cannot read property 'parents' of undefined" , although I get a notification "database restored succesfully" nothing works. The server crashes and I have to manually delete the database from postgress before it will start up again. When I import the database into a second openerp 7 installation everything works fine. What am I missing?

Thanks.

You can't import a database from one release of Odoo to another (ie: v7 to v8).  You need to 'migrate' the database, accounting for data model changes between version - which can be staggeringly complex.  This is either a service from Odoo, or you rely on your own skills or those of the community through the open-upgrade project.

Only upgrades from the same version (ie: v7 in March to v7 in December) are supported via the 'update=all' command-line argument.

Pricing for Odoo service - aka the Publishers Warranty - aka subscription - at https://www.odoo.com/page/pricing

Information on Open-upgrade at https://doc.therp.nl/openupgrade/ 

If you opt to migrate yourself, you are better off exporting everything in your database to CSV files and importing everything to the new version mapping the data models over yourself.  (although I would never recommend this option unless you have a LOT of time on your hands).
