But I didnt do some cross compile from 4 to 7, too much like hard work that! So quite possible to upgrade without repartitioning disc & reloading data. But you might want a bigger root. You might want a newer FFS for performance (can't remember when that came in). ... there'll doubtless be a few other `Gotchas' so if you have problems/ not enough experience/ get stuck. the safe way is a back up, & reinstall. Well, a back up's not exactly a foolish precaution anyway ;-) Good luck.
