Hello,

I am new to Odoo.

I have to make migration from Odoo 8 CE packaged installer on windows to Odoo 10 CE packaged installer.

I made a test on my host:i installed Odoo 8 CE packadged installer the i delete it and install Odoo 10 but i got errors on the server log such as:

ProgrammingError: ERREUR:  la colonne ir_ui_menu.active n'existe pas

It seems there a problem with database.

Do you have an idea how can i make the migration in this case?

Thanks in advance for your answer.
