Upgrade 1.7.5 to 5.X

[Daniel_Rodriguez]

Elasticsearch version (bin/elasticsearch --version):
Version: 2.4.6, Build: 5376dca/2017-07-18T12:17:44Z, JVM: 1.8.0_151

Plugins installed: [none]

JVM version (java -version):
Version: 2.4.6, Build: 5376dca/2017-07-18T12:17:44Z, JVM: 1.8.0_151

OS version (uname -a if on a Unix-like system):

Description of the problem including expected versus actual behavior:
Regarding the upgrade guide to upgrade ES from 1.7.5 to 5X we need to upgrade first to 2.4.
I follow the step describe on https://www.elastic.co/guide/en/elasticsearch/reference/2.4/setup-upgrade.html but the cluster does not restart. The log complains on the mapping for the index.

Please format your code using </> icon as explained in this guide and not the citation button. It will make your post more readable.

Or use markdown style like:

```

```

Please edit your post.

As I said in the github issue, you can't have from 2.x the same field name within 2 types with different definition.

Here index1/Alarm-GardanneDRS has a field named zone_surveillance which conflicts with another type that you have in your index.

Anyway, in 6.0 multiple types are not allowed anymore so I'd say that is the right time to reindex everything and target directly 6.0.

Ok for the answer even it is not that I hope to hear ...
