I purchased the updated version of the plugin and have an older premium version already installed. What is the best way to upgrade to the newly purchased version?
Do I just upload the new files and then get an update option? Do I have to uninstall and reinstall? If I have to do I have to input all of the settings again? Or is there a place to enter a license key which will enable the updates?
You will need to deactivate and delete the older version of the plugin and then install the new zip.
And configure the new License key in your Plugin settings.
