We have install 11g discoverer with weblogic and integrated it with Oracle Apps Release 12.1.3.
Now we are planning to migrate the ERP and 11g discoverer to different server.
Please share your approach for the same.
You may migrate the EBS instance using Rapid clone utility, but in case for Discoverer you will have to install it separately or clone it separately.
Please refer notes/link:
Is It Possible To Clone Discoverer As Part of EBS Clone Process (Doc ID 737937.1)
Cloning Oracle Fusion Middleware
Hope this helps!
