It is always nice to be able to give something a run before committing to it. 
Necessary? IMO, user will be concerned first about data loss, second about 
interuptions in usability, and third about the ability to make an orderly and 
painless retreat if necessary. Does KDE PIM 4 change data or formats? If so, 
is the change reversable? Concerns might be minimized if an intuitive KDE PIM 
data backup/restore method were described as step in the migration. 

If you have a widely divergent basis of KDE PIM 3 versions in use, might 
maintaining all the 3/4 dependencies get complicated?
