error upgrade OE7 to Odoo 8 with demonstration data

[mayjo79]

I create a new DB v7 with demonstration data (only sales module).

After running migrate.py, there are some errors in migration.log :

Upgrades with demo data doesn't work. It's a pending task, but due to the nature of demo load, it can't be done easily.

Sorry for my typo: s/can/can't/ (fixed in previous comment also)
