Hi,
Much of this functionality is now in the USM Portlet.
Alarm Console and Dynamic Views have been replaced by the Alarm Views and System Views in USM.
The Maintenance Mode portlet has been replaced by a new USM-Based Maintenance Mode.
Custom Dashboards and Dashboard Designer have both been replaced by the new "Dashboards" portlet, which is HTML5-based instead of Flash-based.
Finally, Nimsoft Remote Admin has been replaced by the Discovery Wizard, also found in USM.
Hope this helps.
Thanks,
Jason
