You can upgrade to your desired add-on bundles from your existing bundle, just by paying the pro-rated difference between the bundles.
In order to upgrade from your existing bundle,
- Login to https://wpemaillog.com/account/
- Click on the Account menu
- The Account page will list all of your existing orders. Click the “View Licenses” link of the Order which you desire to upgrade.
- Now click on “View Upgrades”. This will list all the Upgrade options that you’re eligible, along with the price calculated at pro-rated basis (you only pay the difference between the bundles).
- You can choose the upgrade from the list and complete the upgrade by making the payment.
