Or you could always do what I do. Titanium Backup all my data apps them My Backup Pro for my call log, sms and mms. I also use nova launcher and back that up. Then I can reinstall my whole rom in under 10 minutes including home screen and widgets.
From v4 to v5 should be no wipe but it does depend if future firmware from Samsung has any system changes. I can't predict that.

Ok, thanks for answering.
Few questions before the switch
1. For nandroid backup I need a Cwm or twm, which you recommend?
2. Titanium backup is for me a mystery : it has far too many options. What to do to backup data of apps (I guess is better to backup data only otherwise it will take forever to backup data+apps).
