Buying renewal versions
If you own a standard, professional or enterprise license of our modules, and your free upgrade period has passed. You want to upgrade the module to a new version. You can then purchase the renewal version of the module if no more than two years have passed since the last purchase. Renewal versions are cheaper than the new license. If more than two years have passed, then you need a new license again.
The renewal license must match the original license. This means that for the standard version you buy the standard renewal version, for the professional version you buy the professional renewal version, and for the enterprise version you buy the enterprise renewal version.
After upgrading the module with the renewal version, the module needs to be reactivated. First you enter your new invoice ID, and after that the module will ask you for the old invoice ID.
