You are right that it now seems to be in the form of an installable addon, and that it comes in two parts for the Odoo-14 branch. *addon* *version* *summary* https://github.com/OCA/OpenUpgrade/blob/14.0/openupgrade_framework[2] 14.0.1.0.0 Module to integrate in the server_wide_modules option to make upgrades between two major revisions. https://github.com/OCA/OpenUpgrade/blob/14.0/openupgrade_scripts[3] 14.0.1.0.0 Module that contains all the migrations analysis and scripts for migrate Odoo SA modules. This looks much easier to install, and to include in the Odoo-14 package than previous versions. The documentation is very out of date, stopping at Odoo-11, but there does seem to be (as above) an active Odoo-14 branch. -------- [1] https://github.com/OCA/OpenUpgrade [2] https://github.com/OCA/OpenUpgrade/blob/14.0/openupgrade_framework [3] https://github.com/OCA/OpenUpgrade/blob/14.0/openupgrade_scripts
