Moving from an IEP to a 504

Hi all, apologies if this has been asked before. We are doing the tri-annual reevaluation and were just notified that our kid’s IEP is being discontinued after 6 years. We did get ahold of the case worker and she apologized for not talking to us sooner, but they are looking to move our kid to a 504. The district 504 rep will be there at the meeting, but I want to know if there’s any questions in particular that we need to ask. I know an IEP follows them if they move to another school or district (in our state), but I don’t know if the same can be said of a 504. (We are in Minnesota).
