I don't think you should be very nervous at all. There are two questions:
1) can 3.1.1 go to 3.2 with no down time. This is very likely, but a wiser head than mine should have final say 2) can 3.1.1 go to 3.2 with < 1 minute of downtime. The is for sure. Neither option involves data loss. ZK is actually really really good for HA operations.
