difference between - APIC Enterprise Module (APIC-EM) and Base App

[Network_Sarovani]

what is the difference between the below 2 ACI Modules ? How do we check which module are we currently using ?

1.Cisco Application Policy Infrastructure Controller (APIC) - Network Insights Base App

2.Cisco Application Policy Infrastructure Controller Enterprise Module (APIC-EM)

as per i know :

1.Cisco Application Policy Infrastructure Controller (APIC) - Network Insights Base App

This is more of ACI for DC switches.

2.Cisco Application Policy Infrastructure Controller Enterprise Module (APIC-EM)

This was OLD one, now merged in DNAC. (before it was used for PnP for Enterprise switches) - not DNAc does all part of SD-Access.
