The UIM documentation has move to the CA Wiki under the DocOps initiative.
In a browser, trying to go to http://docs.nimsoft.com takes you to: http://aws-0ab7d906.ca.com/prodhelp/index.htm, which displays the following:
The CA Unified Infrastructure Management Product Library has moved to wiki.ca.com
For Unified Infrastructure Management version 8.1 or later, user documentation is available at wiki.ca.com. Use the links below to find the latest documentation for your product:
CA Unified Infrastructure Management
CA Unified Infrastructure Management - Probes
Documentation for Unified Infrastructure Management 8.0 or earlier will still be available at docs.nimsoft.com:
The full product library
The Probe Library for Admin Console
The Probe Library for Infrastructure Manager
Embarrassingly, those new links don't seem to work. The ones I now use are:
https://wiki.ca.com/display/UIMPGA/ - probe guides
I know the structure of the documentation has changed for the new Wiki Site too - not sure what to suggest about rebuilding your 100+ links...
