IAM Suite is the OOTB Application Domain created when OAM 11.1.2 is installed. This Application Domain can be renamed after installation but when upgrading OAM to 11.1.2.2.0, it must be renamed back to IAM Suite. If it has been renamed, the upgrade operation will fail with this error seen in the WLS admin logs.

If the IAM Suite Application Domain has been renamed, it is required to rename it back to its original IAM Suite name prior to beginning the upgrade process. After the upgrade, the name can be changed back to a custom name.
