MSS deployment failed NWDS

Hi ,

We migrated from 7.0 to 7.4 Portal.

There are some customizations done in MSS webdynpro JAVA components and it is done in 7.0.

Now we are using same MSS track for deploying in 7.4.  When I created project in NWDS , there is no migration popup came and I build it with no errors.

But when I try to deploy it I got deployment exception : Dc failed.

Version Status : Higher

deployment status : Admitted

Please let me give your inputs in this regard. Thank you.

Regards,

Raghav
