I don't think you'd have to consider migration all the data from Pivotal, but lets assume 10% just in case? Lets say that's 100TB in total (on disk), which you could host with 10x storage boxes from Hetzner, 24 EUR each per month, so 240 EUR in total, which includes 10 unmetered connections (1 per box).
At that price point Hetzner’s dedicated storage servers with enterprise HDDs are cheaper per terabyte and better suited for production work loads.
