For development purposes, we have been running multiple ES 1.7.5 clusters on one VM. Right now, we're in the process of upgrading to ES 6.1. In using the MSI installer, I've discovered that, apparently I cannot do this any longer (ie. the MSI tells me to "uninstall" before I can "install" when I run it a second time). I used to be able to use service.bat install <service_id> and even w/ ES 6.0 there was an elasticsearch-service.bat file I could use. With ES 6.1 even this is now gone from the bin directory.
Is there not still a way to do this? I'm assuming there is and, as such, I have a follow on question regarding Kibana. Namely, how can I setup multiple instances of Kibana for each ES service instance running on this one windows VM?
