Hi, everyone. My name is Sandra and i am from Uruguay, South America. That's why my That's why my writing could be fuzzy. I hope you can understand me.
We are planning to upgrade a cluster using a rolling upgrade model from 7.7.1 to 8.11 Our Solr Cluster is an external Apache-Zookeeper- version 3.5 installed in a Red Hat Enterprise Linux Server release 7.5 with java version "1.8.0_201" We know that we have to upgrade Apache-Zookeeper version from 3.5 to v3.6.2 but not the java version. The doubt is: What about de operation system? Do we have to upgrade it too? thks. Sandra
