Several areas to consider in migration plan.
1)Exits and Usermods 2)PARMLIB changes 3)WLM migration 4)User Catalogs 5)SMP/E 6)RACF and UADS 7)Backup/Backout Work with SE/ISV to develop plan that everyone is comfortable with. You may want to lay down a minimal starter system to build your new system. IBM used to deliver MCNVTCAT as part of system upgrades but for some goofy reason decided to drop support. Alister Grey was smitten enough that he wrote his own RCNVTCAT and placed it on CBT. Brian Westerman does this for a living and if you need support or guidance he'll probably chime in eventually.
