Step4a: Rest system at – Here we can define the time when do we want to reboot the controller and access points. Please note, the controller will be rebooted as per the current time of the controller.
Use “image no-swap” to ensure the primary image does not get swap with secondary. If you intentionally want to swap the image then use the command “image swap“.
(Cisco Controller) >reset system at 2014-07-11 18:00:00 image no-swap reset-aps save-config
System reset is scheduled for Sep 10 18:00:00 2020.
Current local time and date is Sep 10 09:10:19 2020.
A trap will be generated 10 minutes before each scheduled system reset.
Use 'reset system cancel' to cancel the reset.
Configuration will be saved before the system reset.
Step4b: Reset system in – This is used to reboot the controller after some desired time, like in 5 min or 10 min. The minimum time is 2 min.
(Cisco Controller) >reset system in 00:01:00 image no-swap reset-aps save-config
Time period is too short.
(Cisco Controller) >reset system in 00:02:00 image no-swap reset-aps save-config
System reset is scheduled for Sep 10 20:24:29 2020.

It baffles me how very helpful instruction lacks the very information you require. So when it prompts to save unsaved information, do you say Yes or No. The reason I am asking is whether saying Yes, saves the information that was there before you made your changes (in which case your changes will be lost) or saying Yes, saves the changes you’ve just made that you wish to save.
Hi, Saying “yes” will save all the configurations including the recent one since the date it was saved last time.
