Implementing Adobe Customer journey analytics Design Challenges

[AngelD1]

Hello,

I am implemeting `Adobe CJA`.
For some of the domain and sub domain Data layers was not implemented.

My Question is:

Can we progress without data layer (DOM... etc), if yes. what are the challenges we might face in future without data layer or what is the advantages of having Data layer while implementing Adobe CJA.
Anything else we need to take care.... kindly share your expertise.

Many Thanks

What analytics tool are you migrating from?  If you're currently using Adobe Analytics, you can use the Analytics Data Connector to forward event data to AEP.
