Hello Kyle
>>With the method you've outlined (and what I've tried before), if I copy from sandbox to create this, it should work. Without using the SWPM rename tool, shouldn't I only have to make changes to the default, start, and instance profiles, start the system and run BDLS?<<
Yes and also copy the environment variable files for the OS users (<SID>adm and ora<SID>) from the source system and adapt them with the target host name and SID details.
Also the /etc/services entries should be created.
Cheers
