I upgraded 7.10.1 to 7.12.0 and now I have two index but it give me lot of weired problem
Cannot use field [agent.version] due to ambiguities being mapped as  incompatible types: [text]
I have data coming in to both index. but all my viz are now failing due to one or other reason.
what do I change -
Text fields are not optimised for operations that require per-document field data like aggregations and sorting, so these operations are disabled by default. Please use a keyword field instead. Alternatively, set fielddata=true on [system.island] in order to load field data by uninverting the inverted index. Note that this can use significant memory.
