If upgrading to InTrust 10.2 from any version prior to 10.0 (e.g. from 9.6) then you have to ensure an interim step of upgrading to 10.0 or 10.1 FIRST before upgrading to 10.2! Annoying yes, but impossible otherwise. Oh and it normally takes a day to update just a handful of servers.
InTrust is a hetrogenous auditing, monitoring and compliance tool from Quest Software.
