In case of module updates, don’t forget a few points:
- you should use the same folder for your addons upgrades, the best way is to use git or any similar tool
- if your upgrade concerns XML-based stuff, just upgrade the module from Odoo’s application list, but if it’s code, you must restart Odoo. In rare circumstances, I have even seen older python-compiled files remain in place instead of being replaced. So most of the time I delete them
- if you would like to test the new version before replacing the existing one, don’t forget to check the order of the addons folders list: the one containing the new version must be placed before. I know this is obvious but it may happen…
