From My_Cisco_Entitlements_FAQ
Do I still need to use the Smart Account and licensing portals (Cisco Smart
Software Manager) on software.cisco.com or does this give me a single point of
access into all my information?
MCE is primarily built for all non-financial impacting transactions. We are building
functionalities for post-sale transactions that are non-financial impacting.
You will need to continue to use your Smart Account and Cisco Smart Software
Manager portal until all functionalities are replicated in MCE. This will eventually include
the Enterprise Agreement Workspace (EAWS) on software.cisco.com.
