dirty flash CM10?

is it possible to do a dirty flash of CM10.1.3 from MD4, or will i have to factory reset?
I don't have an S3, but guessing that MD4 is the official ROM? If so, then you will need to factory reset. Dirty flash is generally OK for minor/incremental updates without major changes to /system of the ROMs.
