I have an old Elasticsearch v1.5 domain on Amazon AWS, keeping 30 days of logs.
It seems that it's not possible to upgrade it, so i have created a new domain with version ES 6.3.
Now i have Logstash v2.0 logging to the existing ES v1.5 domain, using the
logstash-output-amazon_es plugin, but i can't seem to get it to also send logs to the new v6.3 domain.
As i understand it, i have to upgrade Logstash.
I would like to have a version of Logstash that can send logs to both versions of ES for a month, for a smooth transition.
I have looked at the compatibility matrix, but it does not cover ES 1.5
Before i start testing different versions of Logstash, does anyone know if there is any version of Logstash that can send logs to both ES v1.5 and ES 6.3?
