RFCs not working after Refresh, is this SecureStore issue?

Question

In our landscape we do frequent system refreshes (DB copy). we use to take out RFC table export and then import them back after refresh. every thing was fine till we upgraded to Netweaver 6.0. Now after refresh most of rfc donesn't work (one which have user ID/ Password in them).
Here is my findings till now:
When we goto SM59 and RFC maintenance screen it give below message:
bold "User Password invalid for identifier /RFC/CCMS (see Long text)"
============================
This is what long message is"
Message no. SR128
Diagnosis
Changes to the global key or system data have invalidated the passwords in secure storage.
Procedure
Enter the user password again.
Procedure for System Administration
You can find detailed error messages for the specified ID in transaction SECSTORE.
======================================
In secstore transaction I found this message for entry:
"System-dependent data for entry /RFC/CCMS changed: TRS / WTH"
Long text for this is:
System-dependent data for entry /RFC/CCMS changed: TRS / WTH
Message no. SECSTORE031
Diagnosis
When accessing the secure storage, the system detected that system-dependent data (installation number or system ID) had been changed.
Entry data: TRS
Current system data: WTH
If you receive this message during a migration process, the "Current system data" field contains the old specified system data instead of the current system data.
The content of both fields can also be empty, if the system cannot determine the data in the current context.
System Response
It is no longer possible to access entries that were created with the previous data.
Procedure
Contact your system administrator.
Procedure for System Administration
For more information, see SAP Note 816861.
========================================================
When I check the note it talk about the system copy and migration key, release key. I don't think this is valid in our case.
Now I tried to find out the tables where secstore stores its data:
RSECACHK    Table for Controlling ABAP Programs
RSECACTB     Table for ABAP Access Authorization for Secure Memory
RSECTAB       Secure Memory: Memory for Encrypted Data
At present we backup following tables:
rfcattrib
rfcdes
rfcdoc
rfcsysacl
Please advise if anybody faces the same issue? does anybody have any solution any notes?

Answer 1

I checked all the notes and tables. every thing is correct.
What I think wrong is when we do refresh at that time. SS (secure store) tables from source system come here! we just export and import RFCs but not SS.
All I wanted to know is If we export and import SS tables will this resolve our issue?
can you tell me have you ever did refresh for netweaver? did you face this issue?
appreciate your help
