This issue lists specific CCS tests for Kibana 7.11.0 performing cross cluster search for data in a remote cluster running Elasticsearch version 6.8.14.

• Index Patterns - create index patterns referencing only a remote cluster data:makelogs*
• Index Patterns - create index patterns referencing both local and remote cluster with wildcard *:makelogs*
• Index Patterns - create index patterns referencing both local and remote cluster with comma-separated list local:makelogs*,data:makelogs*
• Discover - shows data from remote cluster data:makelogs*
• Discover - shows data from local and remote cluster *:makelogs*
• Discover - shows data from local and remote cluster local:makelogs*,data:makelogs*
• Discover - filters apply to both local and remote data
• Discover - queries apply to both local and remote data
• Visualize - Lens - works but has some issue Warning in Lens with remote CCS data, Field information can't be loaded #95372
• Visualize - aggregation based Visualizations
• Visualize - TSVB
• Visualize - Vega
• Monitoring
• Reporting - csv
• Reporting - PDF
• Users/Roles - don't test everything as superuser
• ML
• Observability
• Security
• Cross Cluster Replication (CCR)
• Maps - Failed 👎 geotile_grid aggregation was not available yet in ES at 6.8 this was only introduced in 7.0 - This works with both clusters on 7.12.0

• Canvas - SQL queries
• Canvas - Timelion queries
• TBD

@stacey-gammon the CSS version compatibility testing issues don't have a team assigned nor any labels. I'm tentatively assigning them with Meta. Feel free to change these!
