I am having cluster of 3 nodes , and i have to add one new node to that cluster plus i want to upgrade it to 2.2 to 3.0 version. I have some questions, can you please help me.
1. Do i have to upgrade cluster from 2.2 to 2.3 then 2.3 to 3 or is there any direct way to do it?
2. Do i have to do it by 1 by 1 node , what happen if i add new node with version 3.0 first to cluster and other nodes are on version 2.2?
3. This is production cluster so what things i need to careful while doing this?
4. to upgrade from 2.2 to 2.3 only {apt-get upgrade } will do all the needful?
5. for 2.3 to 3 only script way to upgrade it or is there any other ways?
Thanks in advance for you help.
