You may be seeing the logs member mismatch IOS Code, seen that myself some rare case, but still works.
#show switch (give you that mismatch version information)
If that is member ok to work but if that is as standby some of the commands changed, you will have issue when the master fails and switch to new version (of the switch as master) either lower the version of the switch to inline with stack, or upgrade all members higher version - i prefer to go latest version, may have security fixes
Note : not sure the version of code you running, i have given in general suggestion.

as new IOS is already in switches flash and boot variable is set so if we reload the complete stack will all switches comes up with new IOS?
10-24-2024 12:37 PM
sub-number is ok, not the major version mismatch here.

do you think after setting boot variable with new IOS and reloading the complete stack will it boot with new IOS?

Not only boot variable the image should be available in the switches should work all stack member switches.
