Aborting a Software Upgrade During ISSU
You can abort the ISSU process at any stage manually (prior to entering the issu commitversion
command) by entering the issu abortversion command. The issu abortversion command may also be
issued after entering the issu changeversion command while the automatic ISSU upgrade is still in
progress. The ISSU process also aborts on its own if the software detects a failure.
Note If you enter the issu abortversion command before the standby supervisor engine becomes hot, the
traffic might be disrupted.
