Redmi Note 4G: is a wipe needed to go from MIUI v5 to v6?

[cosmik]

Hello,

I have a friend with a Redmi Note LTE, running V21.0.0 (MIUIv5 stable) of the xiaomi.eu multilang firmware. Now, weekly versions MIUIv6 for the same phone are available.

Can I flash MIUIv6 without reinstalling apps/accounts etc? Or should a full wipe plus install from scratch be made here?
