Because MySDN has been decommissioned, the URL in older versions of IDM and IME is no longer

IME.

You can upgrade to the following versions to get the functioning MySDN URL:

IDM 7.0.3

IME 7.0.3

IPS 7.0(4), which contains IDM 7.0.4

Before you upgrade your sensors to Cisco IPS 6.0(1)E1, make sure you have performed the following 
tasks:

Saved the output of the show version command.

I f you need to downgrade a service pack or signature update, you will know what versions you had, 
and you can then apply the configuration you saved when you backed up your configuration.
