Migrate deployed j2ee application to new server

Dear All,

Is it possible to migrate deployed nwds j2ee application to new installed server without original ear file?

Between, is it possible to re-generate the deployed application as ear file or direct copy the /usr/sap/DEX/DVEBMGS30/j2ee/cluster/server0/apps directory to new server?

Any idea..

Thank you.

Regards,

Weng
