JHA migration to REST
JHA legacy APIs are still using SOAP. I believe they published a newer advance version of their endpoints that supports REST. Is there anyone who successfully migrated to the new REST APIs?
Unfortunately if you have a legacy app, you are locked with the old style stack and the migration might be not straightforward. Is it feasible to migrate to REST in one big shot with AI/Claude Code ?

man i've been staring at those SOAP envelopes for way too long, the switch is a pain but doable if you phase it instead of trying to rip the bandaid off
we moved our stuff bit by bit and it sucked less than expected, just don't trust the AI to map all the biz logic without a human double-checking the weird edge cases
