After upgrading the InTrust Server, the following error occurs when trying to gather from the upgraded agents on the Solaris Servers:
Failed to install Agent. Can't compare agents' versions
Solaris Knowledge Pack (as well as majority of other Knowledge Packs) is not automatically installed as part of the InTrust Server upgrade and will need to be installed\upgraded separately.
Run the SOLARIS_KP.10.x.x.x.msi from the \InTrust\Server directory in the InTrust Server installation media.
