I can't remember what 0.90.x was unlike as that was long ago for us, but we recently upgraded from 1.1.0 to 1.4.0.
Look at http://www.elasticsearch.org/guide/en/elasticsearch/reference/1.x/breaking-changes.html additionally pay attention to: - scripting: - replacement of mvel w/ groovy and disabling dynamic scripting by default. We elected to install the mvel plugin manually and change our scripts to identify that they are mvel (lang=mvel) and make some minor adjustments to make compatible (such as use of _score instead of doc.score in scripts). We will do the upgrade to groovy from mvel separately to take care of security concerns w/ mvel. - lot of percolator changes in 1.x - multi field changes in 1.0.0 - disk space allocation decider configuration format changed in 1.x sometime (if you're configuring that) - enabled CORS if you're using HEAD (see https://github.com/mobz/elasticsearch-head/issues/170) In general, I would go through release notes at http://www.elasticsearch.org/downloads/ and look under breaking changes for every version since your last version.
