Upgrading 2s

Hi I'm looking at upgrading my 2s box for Xmas I'm interested in the zgemma i55 or maybe another zgemma box at the moment I run ipab image with username and password would it be possible to just swap my 2s box over to the new box and continue my IPTV with my current supplier. Obviously flashing and installing ipab and reinstalling my username and password.
TIA
WHAT ZGEMMA BOX WOULD YOU USE FOR IPTV?

If you are buying a box solely for IPTV , then get a mag 254/256.Costs around same as L55 but runs IPTV much better

Heard do much nonsense about the Mag254. Google it's specs... the Mag254 has the same memory capacity and CPU speed as the old zgemma sat receivers. The specs are literally identical, infact, the zgemmas is slightly better, yet the myth persists that the Mag254 (not the 256) is superior.
Yeah, ok........
If your getting a mag box, go for the 256.
Just remember you won't have an EPG or bouquets on those boxes - that comes as a shock to most who move from an enigma box running IPTV to one of those.
