The following modules currently do not have a version compatible with the X-Cart version to which you are upgrading. If you want to keep using these modules after the upgrade, use the "Request for upgrade" button to send a request to the module developers so they provide an updated version for their module and make it available via the X-Cart's Marketplace. Once the updated module versions are available, you should be able to complete upgrading your store without losing any of the features you currently use.
