PAR migration from 7.0 to 7.4 NWDI/NWDS

Hi Experts,

We are upgrading put portal from 7.0 to 7.4. We have our portal par applciaiton in NWDI.

We have created a new track in nwdi 7.4 and copied all 7.0 portal par application to new track.

I am able to create project from new track in NWDS 7.4 (NWDS 7.3 eph1 sp12).

There is no error in java file but it bulid failes because of old jar file reference.

When I try to add dc  as dependent dc to my custom dc where new jars are there (e,g com.sapportal.htmlb.jar)  I am not able to see any dc under standard sc (e,gENGFACADE) to choose as shown below.

Is this because the standard scs added to track was not proper??

Thanks,

Karthi
