I'm looking to upgrade my Elasticsearch cluster to 1.4.5 or 1.5 and was curious if this upgrade will break my current codebase.
We are using NEST 1.3.1 in our code and I want to see if this version supports Elasticsearch 1.4.5 and higher? If you could link some documentation regarding this support, that would help me tremendously. Thank you all!
Did you consider upgrading Nest? Within the same major version, it is pretty much always backward compatible. With an older version of Nest and newer version of Elasticsearch, you would miss out on being able to use any new features that the newer version of Elasticsearch may provide. Anyways, you can read about the release notes of Nest here.

My projects java version runs on 1.7.0_71. and my elastic search version is 1.4.3 . Now we want to upgrade the es to 2.3.5. Is it ok to simply upgrade the elastic search version from 1.4.3 to 2.3.5. or should i upgrade the java to 1.8 then migrate it to 5.1 .. because my ultimate target is to for elastic search 5.1 version.
It should be ok to upgrade from 1.4 to 2.3, but it will be trickier (impossible) to go straight from 1.4 to 5.1 or 1.4->2.3->5.x without reindexing.
Segments created two Lucene major versions back are not supported.
So, even if you updgrade to 2.3, there still might be old segments (created in 1.4) when you upgrade to 5.x. There is an upgrade indices API, but as the documentation says it will not be useful for a 1.x -> 5.x upgrade.
Regarding the Java version, yes, you need Java 1.8, at least update 73: https://www.elastic.co/guide/en/elasticsearch/reference/5.1/setup.html#jvm-version
What version of NEST should i use for latest Elasticsearch version (2.1.1). We are planning to release our product in another 2 months and we are releasing with Elasticsearch 2.1.1 and wanted to know the right version of NEST to use
Nest has currently released version 2.0.0-alpha1 which should be compatible with Elasticsearch 2.x. I'm not sure when they will make Nest 2.0 generally available. You can download the pre-release version from here.

You can upgrade your Elasticsearch version from 0.90.x to 1.x in the following way
Cluster restart upgrade process
Before upgrading Elasticsearch, it is a good idea to consult the breaking changes docs.
As per Elasticsearch Documentation before performing an upgrade, it’s a good idea to back up the data on your system.
I am currently using NEST v1.0.2 with elasticsearch v1.3.2. I would like to upgrade elasticsearch to 1.4 without having to change my application's NEST dependencies, but I am having trouble finding any information about compatibility of the client APIs with more mature versions of elasticsearch. Does anyone know if these two different versions of the products will be compatible?
For the most part, yes, but it isn't recommended. Any 1.x version of NEST should, in theory, be compatible with any 1.x version of Elasticsearch. However, we don't guarantee this as we do not continually test older versions of the client against newer versions of Elasticsearch. Any breaking change introduced in Elasticsearch may break the client as well.
However, we do guarantee backwards compatibility between minor versions of NEST. So upgrading to NEST 1.4 will not break anything in your application, and would also allow you to take advantage of all the new Elasticsearch 1.4 features.
I highly recommend upgrading to NEST 1.4 as well.
