Hi All,
I am planning to upgrade from 2.1 to 5.x.
-
I want to decide on 5.x version and I can see that 5.2.2 is the latest version available as of now. what are the factors that i need to consider on deciding a version in 5.x. can i directly go with 5.2.2 assuming it is best among 5.x versions?

The migration plugin Elasticsearch Migration Helper v2.0.4 works with only 2.3.x and 2.4.x.
Does this mean, i have migrate from 2.1 to 2.3.x (or 2.4.x) and then migrate from 2.3.x (or 2.4.x) to 5.x
or can i directly migrate from 2.1 to 5.x
How can i check with the help of migration helper if there are any issues with 2.1 to 5.x upgrade
