Upgrade completed with errors. Review the upgrade log file located in C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\LOGS\Upgrade-20180220-162221-353-19435b7e3e40479183e3ca8d9f3155fa.log. The number of errors and warnings is listed

To diagnose the problem, review the application event log and the configuration log file located at:C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\LOGS\PSCDiagnostics_2_20_2018_16_22_10_998_970437191.log

The behavior is observed when the web application is created with farm build level 16.0.4456.1000


The corrective action to perform is to Enable the custom tiles feature to force the creation of the Custom tiles list to move past this road block in running PSConfig.
