The ISSU process has been completed. At this stage, any further Cisco IOS software version upgrade or
downgrade will require that a new ISSU process be invoked.
Aborting the ISSU Process: Example
The following example shows how to abort the ISSU process manually:
Router# issu abortversion b disk0:c10k2-p11-mz.2.20040830
If you abort the process after you have entered the issu loadversion command, then the standby RP is
reset and is reloaded with the original software version.
