@siteimpulse probably not 5, but yes, the free version was unavailable for a few years, so the engine advanced a lot since then through the full version’s continuous development. But I know that authors can help in manual migration of the old tables.
The best/fastest way to get support in that would be to open the chat on https://mapsvg.com and send the authors a message, or use the support chat that is now embedded in the plugin.
