Already existing adapter modules in Decentralized Adapter Engine(urgent)

hi 2 all,

I have installed a Decentralized AE.

I wanted to know whether i can use already existing modules in XI directly in my communication channel with my non central DAE as the adapter engine.

Or i have to deploy SCA of those already existing modules also ??

If i can use how to write that in modules

regards,
