Dear,

I never used the openupgrade module.

If you have any tutorial to follow it, I will appreciate.

Best Regards

Dear,

To follow the instruction. Do I need to add the odoo-addons for odoo16.0 on the same server running odoo 15.0 for the migration ?

Best Regards

I am back regarding the upgrade of odoo 15 to odoo 16.

I am facing an issue :

This module is not installed in odoo 15.
