Hi there,
Finally I have managed to upgrade from 2.36 to 2.39, even 2.40.
I have spent many different ways to upgrade, and sharing my steps to upgrade incase if anyone need to use in the future.
Before to start everything just backup all your DB
- Remove all your custom jobs scheduled - ver2.36. Just in case create a backup of current state
- Remove all your analytics - ver.2.37 - Just in case create a backup of current state. I used it to revert DB when upgrade failed
- Upgrade to 2.37
- Update your analytics - Just in case create a backup of current state
- Upgrade to 2.39 - Just in case create a backup of current state
- Upgrade to 2.40
So hopefully it will be useful for someone
Regards,
