We've gotten all the files from Avaya's support site.
Any thoughts out there?

Hello LV91, you can just migrate between VOSS and BOSS only on ERS4850 switches with VSP4000 Conversion KIT where the switches has the Part Number AL4800.
VSP4450 and VSP4850 with the Part Number EC4x00 can NOT be migrated to ERS BOSS software!
The minimum software release version for VSP4450 is VOSS 4.0.50! VOSS 3.0 only supports the VSP4850.
