Upgrade
The upgrade from Essentials Freemium to Premium version is as simple as installing the premium package without uninstalling the freemium one. The upgrade process must be done manually, after that automatic updates will take over.
Upgrade to v2
Upgrading Essentials v1.x to v2.x should be planned carefully as it's a major version release only compatible with YOOtheme Pro 4.0, which is itself a new major release. Follow these steps in the given order.
- Make a full, restorable backup of the site.
- Head over to System > Plugins and disable the Essentials plugin.
- Upgrade YOOtheme Pro to version 4.x.
- Upgrade Essentials to version 2.x.
- Head over to the plugins manager and enable back the Essentials plugin.
Thoroughly clear all caches, and test. If anything goes wrong, restore the backup and reach out support.
