2. Run ZPHIRNM on the previous SYS
nn
 (in this example, SYS20). The previous 
SYS
nn
 is the configuration that was running before the current configuration.
3. Rename the current SYS
nn
 (SYS00) and CSS
nn
 (CSS00) to an unused SYS
nn
(SYS01) and CSS
nn
 (CSS01), respectively. For example:
> FUP RENAME $SYSTEM.SYS00.*, $SYSTEM.SYS01.*
> FUP RENAME $SYSTEM.CSS00.*, $SYSTEM.CSS01.*
4. Rename the previous SYS
nn
 to the name it had at the completion of the Apply. 
For example:
> FUP
> RENAME $SYSTEM.SYS20.*, $SYSTEM.SYS00.*
> RENAME $SYSTEM.CSS20.*, $SYSTEM.CSS00.*
5. Perform a system load on your usual SYS
nn
 (SYS00), which now contains the 
revision before the last update.
6. Restart DSM/SCM.
7. Update the DSM/SCM database with the new SYS
nn
s:
a. Before the next Apply to the system, run Verify Database so that DSM/SCM 
can resolve the current names of the SYS
nn
s.
b. Create an independent snapshot of the target.
c. Receive the independent snapshot into the host database.
