Configurations settings were lost after Image Server upgrade.

Problem : After upgrading from IS 3.6 to IS 4.0 we lost the configuration settings in Capture for production repository. User were unable to scan using FileNet Capture.
Solution: Follow below mentioned steps :

1).Add an entry into Hosts file c:\windows\system32\drivers\etc to point to old IMAGE server as shown below :
XXX.XXX.XXX.XXX stgeorge-filenet-nch-server
2).Then open the repository in Capture Professional 4.1 using sysadmin username and password and copy all the configuration settings to Local repository.
3).Remove or comment out the entry done in Hosts file in step 1. Open the same Image Server repository in Capture Professional with SysAdmin credentials and copy config folder from LocalRepository to the missing production repository. Close the Capture application and log back in again with scanning user credentials.Test the application by scanning few batches. Old settings should be used by scan and other components.
