The following message should be in upgrade log in a browser or in the /var/log/plesk/install/autoinstaller3.log file:

CONFIG_TEXT: Components and product check results:
Upgrade is finished
Congratulations!
The upgrade has been finished. Plesk is now running on your server

More information about Plesk upgrade can be found in Plesk documentation.

Note: On Plesk for Windows, logs are located in C:\ParallelsInstaller\autoinstaller3.log

Plesk > Home page should show installed Plesk and update version.
You can check installed components by the following ways in Plesk Interface:

1. Go to Tools & Settings > Server Components and verify installed components
2. Go to Tools & Settings > Updates and Upgrades

Plesk and update version can be checked directly on the server:
For windows:
