The log analytics page (Log Analytics - Analytics Platform - Matomo) claims that piwik can import historical logs from awstats:
Migrate from AWStats and Urchin easily by importing your historical logs into Piwik. Invest in the future by importing your logs in Piwik.
But I can’t find this option in the import_logs.py script - is there another script or option to that script that I’m missing? Without being able import old data it will be a hard sell to move existing users over to a new system.
