Thanks @magnusbaeck, much appreciated advice.

I also got some advice from @andrewkroh in the other topic [here](https://discuss.elastic.co/t/topbeat-beat-hostname-analyzed/36930):

> @plonka2000 You would need to re-index your existing data. It takes a bit of work and the way you accomplish the task varies by your technology. Basically you read the data out of ES then re-write it to a new index. See the links below.

Thanks very much @andrewkroh, I'm going to investigate the possibility of reindexing, and if it proves too complicated/time-consuming/scary I may go with the original 'delete and create' solution (I'll chalk this one up to experience and better planning next time).

Thanks to you both for your help.
