Moving from domain to domain in EV - No. 2

This forum post is related to article: https://www-secure.symantec.com/connect/forums/moving-domain-domain-ev

We are considering running a similar scenario. Questions:

* Did the RegKey value change resolve the issue with Discovery Accelerator originally posted?
* Does Discovery Accelerator maintain its "Chain of Custody" structure, Permissions, configurations, etc?
* Will this process work if a "Trust" has not been established between two domains? (e.g. Moving from a LAB environment to Production)
* Does anyone know if this type of implementation is supported by Symantec?

Thanks for your help!
