Hi, I'm using elasticsearch version 2.2 and also 6.4. Since indices in version 2.2 cannot be directly reindexed to 6.4 i'm running both version at same time and once if data inside version 6.4 is large enough, i will stop ES2.2. Thats my plan. I just run a Aggregation to compare the execution time…

Aggregation response time is slow in ES Version 6.4
