PBatavia01

I'm getting back to Polisy after a long while, since I want to move over to IoP. I'm currently at PG2. After doing an update, I show that I'm at Version 2.2.13, Frontend Version 2.2.9-5, ISY Version 5.3.4. I assume I need to update to PG3 via SSH? I tried to find a wiki page with instructions, but failed. The closest I could find was this: PG3 Instructions - Universal Devices - The Most Powerful Automation, Energy Management, and IoT Platform (universal-devices.com) which has a series of install and service commands. But before I do this, I wanted to confirm I wasn't missing anything else. Thanks for any help or pointers!
