We’re trying to upgrade from an old piwik (pre-3.05) to Matomo 3.13. Can the upgrader handle the database upgrade? Or should we step to an interim Matomo, like 3.05. Then move up?
Note: we have some custom variable in our database.
I’ve tried, and gotten a memory limit failure. (Not a php.ini memory limit–it’s possible we need a bigger server.)
