We are planning to upgrade kibana from 3 to 6.2
I have read that the dashboards arent compatible.
Need suggestions as to What can the best approach for the upgrade.
Also, what kind of changes are done that make the 2 versions incompatible? reason behind asking the question is to understand how difficult would it be to write a mapper code that would convert the json files of version 3 to that of version 6.2
