Thank you gary. I followed the steps but ran into an issue
1) first, we backed up the esourcing and nw database
2) then on the brand new target system, we restored these databases using db tools
3) Then via sapinst, I created a distributed sap netweaver system using the "db backup method" and used the copy of source netweaver database.
4) then I installed e-sourcing on NW the system and ran configure utility to point to the newly copied esourcing database
5) redeployed fcsourcing.ear file
Now when I bring up the esourcing application page --- it shows a page that says "new user registration" and also it wouldnt allow me to login as system user with the password from the production system !!
any ideas ?? how can I check that it is pointing to right db ?
