Migrate from S3 Easily with the R2 Super Slurper
blog.cloudflare.comMigrating from S3 has been always easy, as long as you agree in paying the awful amount of money AWS is asking you to do it. But using R2 as a lazy loading layer for S3 seems like a very clever trick move that can alleviate the process a lot by spreading the payment in a longer period of time.
And who knows, maybe after some months the remaining data can be considered cold enough to just archive it.
edit: fix sentence.
