There shouldn’t be Jake. I'm running MOD-54's for my sysres volumes and have been for years. Probably the only issue you might have is if you are going from a multi-sysres config where you had multiple system symbols for catalog purposes, you'll just have to fix that to all use either ****** or &SYSR1.
