Motorola is reporting on their support forums that there’s no official upgrade path available for leaked 2.2 Droid X ROM.
No worries though, if you’ve saved your original 2.1 ROM, you can always restore it, upgrade to the official Droid X 2.2, and should be back in no time.
WARNING: Do NOT load the leaked 2.2 upgrade that has been floating around on the Internets. There is currently no upgrade path from that load to the official 2.2 load that will be released by early September. Unless you have some plan to flash your phone back to the current official load, you could be stuck on the leaked version.
