Upgrading Haraka

[atxfun]

This may sound like a stupid question to some of the folks reading this but I have not been able to find where this is documented. What is the proper way to upgrade haraka? I just want to make sure I am not missing an important step (assuming there is more than one step).
Is this enough?
npm install -g Haraka

Would I also need to do this again?
haraka -i /etc/haraka

And what about upgrading any plugins that I may have installed? How do those get updated? Would this do the trick?
cd /etc/haraka
npm install

There's a number of ways to go about this. I upgrade Haraka by deploying a new version. I have a persistent /data directory for storing the config, queue, and logs. Everything else within the Haraka [container / vm / jail] gets rebuilt with every deploy.
