The following example shows how to use issu changeversion with the "at" command option to schedule
an ISSU upgrade procedure to automatically start at the specified time. This example specifies that the
ISSU upgrade should be started at 16:30 (24 hour format).
Switch> enable
Switch# issu changeversion 1 bootflash:y.bin 11 slavebootflash:y at 16:30
% 'issu changeversion' was executed at [ Aug 12 16:27:43 ].
% The planned ISSU changeversion is to occur in (hh:mm:ss) [ 00:03:00 ] at [ Apr 12
16:30:43 ].
% Current system time: [ Aug 12 16:27:43 ]
% Planned upgrade image: bootflash:y.bin
% To cancel the planned upgrade, please execute 'issu abortversion'
