Getting ready

Stop any instance currently running with the Odoo source you are about to update.

Make a backup of all the databases you care about in case something goes bad. This is obviously something you need to do for production databases. Refer to the Managing Odoo server databases recipe for instructions.

Then, make a note of the current version of the source you are running. The best way is to create a lightweight tag using the following command:

$ cd ~/odoo-dev/odoo
$ git checkout 11.0
$ git tag 11.0-before-update-$(date --iso)
