Replatforming off of iSeries / IBM i

We'd like to replatform off of our IBM i and move JD Edwards to a Windows platform.

Has anyone here undergone that journey? Any tips, tricks, gotchas, etc. that you can share?

We're very much in the discovery phase of this project but would like to start lining things up so we follow best practices, lessons learned, etc.

Any and all help would be appreciated! Thank you!
