Upgrade 2X 3750X stack to 12.2(58)SE2 one by one

Hi,

I have a stack of two 3750X switches and want to upgrade to 12.2(58)SE2 version, but this will take long time due to microcode upgrade as well and disrupt the network; is there any way I can upgrade one by one?

Also, currently the switches are running a .tar image; can I go ahead and use a .bin image when upgrading?

Thank you

It doesn't make any difference.  The micro-code will be upgraded and it'll take around 45 minutes to upgrade both units simultaneously.
