Hi,

we have a single instance of ELK running.  
I want to update from 5.1.2 to 5.3.1.

The upgrade instructions I found are for clusters.

Since I cannot avoid downtime with a single instance, what do I need to do?  
Just applying my configuration to the new server version and start the new version?

Thanks,  
Andreas

Yes. Shutdown the old version, upgrade in place, start the new version.
