IOS Upgrade 12.2 to 15

[Mandla1991]

Good Day,

I have multiple C2960-48PST-L switches which are all running IOS 12.2(50)SE5, I would like to upgrade them all to their latest version 15.0.2-SE10a and the TFTP server has been configured.

I wanted to confirm that a direct upgrade from IOS 12.2 to 15.0.2 is possible and if any configuration will be affected so that there is no down time.

There will be downtime as a switch IOS upgrade for the 2960 platform requires a reload.

Your configuration will not be affected (other than the line that specifies the boot image).

Thank You.
