Redis Upgrade from 3.0.7 to 5
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;

I have plenty of Sentinel and Cluster servers running 3.0.7 and need to upgrade to 5. I cannot afford downtime. Can someone please advice me how to do it?
Some DBs are so big that the servers cannot allocate a new/second instance in case of the best solution here is lunching a new Redis 5 on the same server and set it as slave of the 3.0.7.
1) Can I just go directly from 3.2 to 5 or do I need jump into 4 first?
2) Reading from here that need a massive restart when upgrading from 3.3 to 4. Any way to avoid downtime? How to reestablish the original cluster data? Backup and restore?
Any advice is welcome.
