Hi SS,
Thanks for the information.
Here I am not touching my DB Instance which is in RHEL 6.5 Clustered environment.The domain will remain same for the DB instance.So I feel there is no need to system copy as through system copy I will only be able to take DB Instance export ; not the PAS export.
The app servers are in separate host.I can reinstall them in the new domain but I want to check out the option about Primary application server.One option can be re installation in the new domain.But is there any other option by which I can bypass the reinstalltion at least for primary app server?
User ids will not be problem as there is a trust relationship exist between old and new domain.
Best Regards,
Debaditya
