Notes from Carrierwave to Active Storage

I recently migrated Day of the Shirt, my graphic t-shirt sale aggregator, from storing image attachments with Carrierwave to Active Storage. It went ok! 👍There were a couple of things driving this migration, though Carrierwave had served me very well for nearly a decade:For budgetary reasons, I was moving the storage service from S3 to Digital Ocean Spaces. I knew I’d be doing some sort of data migration regardless.I was using some monkeypatches of Carrierwave v2 that weren’t compatible with Carrierwave v3. So I knew I’d have to dig into the internals anyways if I wanted to stay up to date.I generally trust Rails, and by extension Active Storage, to be reliable stewards when I take them on as a dependency.
