I am using the elastic search of version 0.95 from the past few years.
Now I want to upgrade my elastic search.
My worry is, is there any code change required to upgrade elastic search.
And can I directly upgrade to v6 from v0.95?
My application is large-scale application and there are vast methods in it.
And I am trying to upgrade via rpm install.
Can anyone explain clearly what are steps I need to follow from end to end
I've already tried to upgrade v6 and v2, but it's not working.
