The recipe is something like this
1. install knapsack
2. create new index. Example
curl -XPUT 'localhost:9200/newindex'
3. create new mappings
curl -XPUT 'localhost:9200/newindex/newmapping/_mapping' -d '{ ... }'
4. copy data
curl -XPOST
'localhost:9200/oldindex/oldmapping/_push?map=\{"oldindex/oldmapping":"newindex/newmapping"\}'
