D365FO on-premise update to 8.0

Hi All,

We have deployed default D365FO on-premise environment (Platform update 15, application update 7.3).

I have managed to update it to PU15 by installing an update in LCS, but now I want to update application version to 8.0.

The problem is that I can't find anything like "8.0 update" in LCS "Add updates" section.

Can someone please give me some guidance on how it should be done?
