Hi Matt,
I would definitely start with the DFSMSrmm Redbook https://www.redbooks.ibm.com/abstracts/sg246241.html . IBM does have a Software Migration Project Office, SMPO, that can do this for you. They also have some conversion programs to help with this process also.Diane Chidgey is a contact in the SMPO that would be able to help you with setting up a contract for converting you and or providing the conversion programs.
Hope this helps.
