Changing system name - does it affect anything?

[Ranga Nathan]

I am flash-copying our test  zvm 5.2 environment to create a new test 
environment, which eventually will become production. After I do the 
flash-copy, I want to adjust the system parameters including the 
"System_Identifier_Default".  I did notice that I had to specify the 
system id when installing/configuring DVHMOVE, in the CONFIGAA DATADVH 
file. When I change the system id, are there other places that will be 
affected?
