PowerShell Universal version 3.2.8 upgrade to 5.5.4 (IIS)

Product: PowerShell Universal
Version: 3.2.8

Hi there,

I have tried upgrading PowerShell Universal version 3.2.8 (IIS install) to the latest 5.5.4 but keep getting IIS errors. I have tried upgrading the databsae and changing reference appsettings.json file in UniversalAutomation folder. I am presented with the first run page and then subsequently it get stuck on “PowerShell Universal is loading..”.

Luckily roll back worked but I need to get the version upgraded. Can you send a link or steps to upgrade the version. Please let me know items that I need to be careful of.

Thank you
Tarun
