Has anybody actually tried AIStor ? Is it possible to migrate/upgrade from a minio installation to AIStor ? It seems to be very simple, just change the binary from minio to aistor: https://docs.min.io/enterprise/aistor-object-store/upgrade-a...

Is AIStor Free really free like they claim here https://www.min.io/pricing, i.e

  Free
  For developers, researchers, enthusiasts, small organizations, and anyone comfortable with a standalone deployment.
  Full-featured, single-node deployment architecture
  Self-service community Slack and documentation support
  Free of charge

I could use that if it didn't have hidden costs or obligations.
