Information hub about Odoo Version Upgrade
Odoo release cycle: https://www.odoo.com/page/odoo-long-term-support
Odoo Enterprise version upgrade: https://upgrade.odoo.com/
Odoo Community version upgrade: https://oca.github.io/OpenUpgrade/intro.html
Current state (15.0)
T-2 version support (eg: if current version = 15.0, than T-1 version = 14.0; T-2 version = 13.0)
New major Odoo versions are usually released at the begining of October each year as part of the yearly Odoo Experience event
After release expect around:
2-3 months for Odoo S.A. to prepare upgrade path for Odoo Enterprise (they are getting quicker every year)
6-9 months for OCA’s openupgrade (although some apps are never finished…)
Much easier than used to be, but not as simple as one click
It is not like upgrading your Windows, needs professional assistance
Can be time consuming with many customizations
