Need to migrate a 1000 REST API Data Connections to Code Repositories

Hey.

So basically we have a 1000 data connections based on a REST API Source. They’re still functioning fine, but this type of source is being sunset and we’re slowly getting pressured by our admins to migrate to Code Repository based external transforms.

Has anyone here dealt with anything like this? We’ve already established what such an external transform would look like, as we’re using them for all our new connections, but we’re afraid of having to migrate all the 1000 old connections by hand.

Is there anything that can be done to make this migration process as painless and as automated as possible?

Thanks a lot!
