There is a script to help with the conversion in the emoncms/usefulscripts repo

I have never used it and a quick search here on the forum for “phpfiwa_to_phpfina.php” showed 2 posts that had an error with Redis, you could try commenting out the redis test and force a conversion without using redis if it is a problem.

You might find more info using other search terms, there is also the archived forum.

This “Upgrading mysql, timestore, phptimestore feed engines to phpfina and phptimeseries” post might be helpful.
