I am doing the update from 7.3 to 8.0 I am trying to figure out how to apply the database update package. I was able to apply in in DEV through LCS, but in UAT this package is not visible and LCS Apply Updates shows as "To apply Data Upgrade packages, please open an upgrade request." Where do I make this request from, I am not seeing this specific request.
I assume you mean Tier 2 under "UAT". There is a button "Upgrade" near "Maintain"on environment's details page. However, it is available only if customer is live; otherwise you have to simply delete environment and re-provision new 8.0 and deploy upgraded code.
Hey, have look this blog, I have write in detail about 2-tire environment upgrade
