Hello!
We are moving all our metrics from Graphite [1] to Prometheus [2]. See the master task for some details [3]. We are now working on porting all those metrics for elasticsearch [4].
This means that we'll need to update our dashboards to start using those new metrics. During the transition, I'll keep the existing dashboards, but create a copy to migrate the metrics. For example, the "Elasticsearch Percentiles" [5] dashboard has a copy named "Elasticsearch Percentiles - Prometheus" [6].
Those new dashboards should behave in just the same way, but please let me know if you find any incoherence!
Have fun!
Guillaume

Will the old dashboards/URLs always keep functioning for past data?

Always is a long time! We still have plenty of metrics on graphite, so graphite is not going away any time soon. Having a view on long term trends is useful, if only for capacity planning.
That being said there is a cost associated to keeping graphite alive and to keep data forever. So... future will tell, but there will be discussion at that time.
