The lift-and-shift that took six months
On paper it was the simplest kind of cloud migration: move one third-party server to a VM in AWS, same software, newer version. It took six months. The move was never the problem. The software assumed an environment that has mostly disappeared, the vendor who alone was allowed to install it couldn't operate the OS it ran on, and everything an operable system needs (readable logs, a health signal, automatic recovery) had to be built from the outside, around a box we weren't allowed to open.
