I have a cluster with ~2 TB of data with a lot of very small documents. I need to migrate from 1.x to 2.x. The problem I am having is that when I do the restore from snapshot it uses the original mappings for the data ignoring the templates.
I need the new mappings! If I try and do the migration using logstash it takes a massive amount of time - more than we can support. Is there another export/import method I can use?
