Upgrade Kibana from 4.4.1 to 4.5.3

I currently have the Kibana version 4.4.1. I noticed that a new version has been released that fixes the tile map visualization (4.5.3). I want to upgrade to that while still keeping the dashboards and indexes. What are the steps to upgrade?
I could not find anything in the docs.

How did you install KB to start with?

I used the yum command to install the rpm package..Does the upgrade follows the same process?

Yep, just update the repos to point to 4.5.

Thanks! Worked like a charm.
