How to Switch From NextGEN Plus to NextGEN Pro
If you find that you'd like to upgrade to NextGEN Pro and you're currently running NextGEN Plus, all you'll need to do is submit a support ticket through your members account to upgrade your membership, and once we've adjusted your account you can login and download NextGEN Pro. To switch, first deactivate and then delete NextGEN Plus (do NOT delete NextGEN Gallery!). Then go to Plugins >> Add New > Upload, and select your NextGEN Pro .zip file > Install and Activate! You're done! 🙂
SWITCH FROM NEXTGEN PRO TO NEXTGEN PLUS
This would be the same process. We'll first need to make the adjustment to your membership profile, and then you will remove NextGEN Pro from your site and then install NextGEN Plus.
