Are there any precautions to take before upgrading from 0.9 to 1.4?
Different data types?
Different API calls?
etc...
And, what is the best way to upgrade? Can we just add a node at the newer
version and let it pull the data?
Thanks.

I would be interested too, we are using the same 0.90.7 version.

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 [Elasticsearch Platform — Find real-time answers at scale | Elastic](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
[ES Head is not working with elasticsearch-1.4.0.Beta1 · Issue #170 · mobz/elasticsearch-head · GitHub](https://github.com/mobz/elasticsearch-head/issues/170))
In general, I would go through release notes
at [Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/downloads/) and look under breaking changes
for every version since your last version.

The most surprising part of my upgrade from 0.90 to 1.0.1 was the drop of
indexing performance. So, yes, I’m also interested to know any gotchas.

Also, forgot to mention... if you have native scripts, they will
mysteriously throw Unsupported Operation exception whenever invoked. Looks
like they made a mistake in 1.4.0 (that is now reverted on master), that
requires you to override the setScorer in native scripts. It's ok, I just
wish they documented in breaking changes.
