How to upgrade when AWS EBS deployments failing

Tried to jump from 0.26.2 to 0.28.1 on AWS EBS using deployment of the pre-built EBS config for 0.28.1. Deployment succeeded, but the application state kept tick-tocking between WARN and OK. Metabase never finished upgrading (I waited an hour), so I rolled back to 0.26.2. Logs were completely unhelpful.

When automated deployments won’t work, what’s the next best/simplest way to upgrade Metabase? Our application DB is now sizeable and we have quite a few users/questions/dashboards.

Sorry I’m not using that deployment option myself - so can’t be of much help here apart from pointing to that if you search for “aws upgrade” in here you’ll find other related threads:
