Solaris 7 audit trails are incompatible with audit trails that have been generated in the Solaris 2.3, 2.4, 2.5, 2.5.1, 2.6 operating environments. You cannot use the praudit and auditreduce commands in the Solaris 7 operating environment to process audit files that have been generated in the Solaris 2.3, 2.4, 2.5, 2.5.1, 2.6 operating environments.
Workaround: Process audit trails only on the same release of Solaris on which they have been generated. This problem is addressed by the following Solaris 7 106832 patch.
