C4C - ECMS ( Content Repository ) integration with NonSAP ECMS system

Dear Experts,

As far as we know there is no out of the BOX integration scenarios with content repository from C4C , however as per my understanding that should be doable.

Since many companies have already their content repositories set up for storing documents.In our case we need to integrate something like that and we dont want to replace the current attchments functionality we just want to change the PHYSICAL storage to our content repository.

Is this possible? Has some one tried to integrate C4C with nonSAP(or even SAP's xECMS) content repository. It will be very helpful to discuss on how-tos and also to discuss pros and cons!

Looking forward for a fruitful conversation.

Regards,

Dhruvin
