BI Platform 4.2 Disaster Recovery setup

I am currently trying to setup our BusinessObjects BI Platform 4.2 Disaster Recovery environment. I could successfully:

- restored the Repository SQL Server database to a DR server

- copied the FileStore folder from PD to DR

- completed the steps provided in the SAP note: 1275068 and reset SIA.

The method in the above sap note involves resetting the services that run on the report server (request port changes, creating additional AdaptiveJobServer, Creation of server groups, other miscellaneous setting, etc.). Is there a way to restore the repository database and filestore to a DR server without wiping out all these settings?
