PI 7.11 sp6 system copy causes target sys to register with source

Question

Experts,
We have a PI 7.1 (EHP1, sp6) PI system based on AIX 6.1 OS and Oracle 11g.
I recently did the standard PI system copy from a prod source (PIP) to a training target (PIT).
I used the most recenty PI system copy guide that is specific for PI 7.1 EHP1
I did not run into any major problems doing the steps of the itself. 
I did the usual "post" steps, documented in the guide that really are done on any NW system. 
Then I got into the specific "PI" post steps and that's where I now have a problem.
I could not run the "wizard for post copy" since I'm on 7.11sp6.  Yes, I know they "downported" it but I don't have those latest LMtools type packages.  Anyway, I'm OK with that. 
I followed all the steps, fixing my RFCs, JCos, Destinations, cleaning up SLD, SLDAPICUST, creating new business systems...etc.
My big  problem is with the exchange profile.  Yes, it's easy to change all the SIDs and hostnames using the search tool for all the parameters in the exchange profile, but the one I COULD NOT CHANGE was the "ABAP Connection".  In there right after the copy was the hostname of the prod system, the client, and the user PILDUSER.   I attempted to put the hostname of my target (PIT) system, but I would get the error:
RFC 399 unable to connect
I'm certain the user is NOT locked and the password is correct for PILDUSER. 
Worse yet, If I left the hostname in there that was set to "prod", then when I changed all the other values in the "parameters" section of the XI profile, then it actually changed my PROD system!!
If I keep the ABAP connection to PIT, then the entire exchange profile disappears for PIT.
Also, now my PROD system shows the PIT system as a "non-central adapter engine".
Ughh!  I'm totally stuck.  I'm not sure what to do. 
It's as if the PIT (PI training) system somehow is linked to PIP (PI prod).  It's like PIT doesn't think he is his own box...
Any ideas?  I'm resisting opening a message because this will be so hard to explain to sap support.

Hi Nick,
We went thru the same issue. Fortunately, it was between Dev to sandbox. I stopped the dev system and changed the exchange profile parameters to  sandbox hostname and brought the Dev up to fix the issue.
Prod showing as Non-Central Adapter engine :- Check your Business System in SLD and In CIM Instances in SLD, check your XI Integration server assigned to right Business System.
Note 764176 - Error in XI due to inconsistent SLD contents :- helped me come over PI post step issues.
Thanks,
