The way Clarity works is the install commands will run two parts: 1. Application upgrade 2. Database upgrade.
If it fails on step 1, you have to rollback the filesystem and run install again
If it fails on step 2, you have to rollback the filesystem and database and run install again.
Any other steps are not supported and admin commands are not supported for upgrading the database. They will not upgrade the database as the commands are deprecated in Clarity version 13+ and do not properly work.
If your install fails, you have to follow the steps above, there is nothing else that can be done.
We at Clarity support cannot review any admin logs as the admin commands for an upgrade, and separate database upgrade is unsupported. Only 'install' command should be used
