I can’t update to Hustle 3.x. It’s actually not a new issue, since the release of the version 3, I tried to update, but it completely crash my install, I had to remove the plugin and re-install the former one (2.x).
There was a new version today, thought it might work this time, but exactly the same happened. My website is hosted by WPEngine (so, that’s quite a good hosting) and they had no idea what’s going on, the migration process seems to looping forever and then the server is out of memory.
The issue occurs once the update is done, the plugin starts its migration process.
As you can see above, in the logs, it seems that this migrations is made through WP-Cron.
