Update redis for noob

Good morning,
unfortunately I found myself managing a server with redis without any warning due to a sudden lack of whoever managed it before. They asked me to update it but unfortunately I know absolutely nothing about this software. The thing I did is see the history to understand what had been done and try to understand.
This is what I found.

tar -xvf redislabs-5.0.2-20-rhel7-x86_64.tar
./install.sh -s /var/run/redislabs
yum install redislabs-5.0.2-20.rhel7.x86_64.rpm

and this
rpm -q redislabs

redis-cli --version
redis-cli 4.0.2

redis-server --version
Redis server v=4.0.2 sha=00000000:0 malloc=jemalloc-4.0.4 bits=64 build=7813b54306bf9e3e

My need is to update it to version 6 as it was done in production.
Can you help me?
Thank you in advance and I understand a very special situation

It seems like you’re using Redis Enterprise, it’s better you contact Redis support for more help.
