During the update process of NetBackup 8.0 to NetBackup 9.0.0.1. error occurred:

During the update process of NetBackup 8.0 to NetBackup 9.0.0.1, the following error occurred: The C:\Program Files\Veritas\NetBackup\var\global\i_nbdbinfo.dat and C:\Program Files\Veritas\NetBackup\var\global\wsl\config\web.conf files were updated independently. The i_nbdbinfo.dat file was modified after the web.conf file. This test runs when you upgrade the NetBackup master server from 8.0 to a later version. This test checks for a match between the web services (nbwmc) update time and the NetBackup database (nbdb) update time. Specifically, it checks the time stamp of the web.conf file and the i_nbdbinfo.dat file. The times must either match or the web.conf file can have a later update time.
