Elastic Restore Help Please

Any ideas yet @aaronsachs , @konrad or @mpfz0r ?? What we are talking about here is really the ability to combine multiple Graylog instances. This seems to me like a use case that should be documented somewhere. Recovering from a disaster is a process that, to me anyway, looks markedly different from building a fresh instance to migrate your data to. One is planned, and the other is not.
