What is approach for upgrade boot image for e.g I am using default boot images let say BOOTX86 which consists of all network drivers now new requirement few network drivers needs to add. So need create same replica (copy BOOTX86) package add new drivers distribute into DP. Mention same in task sequence test new boot image? Or add new network drivers into boot image (production) update boot image? My question is if edit existing boot image after that I need to update meaning it will copy or redistribute to all DPs? in case if any issue complete PXE setup will not work due to boot image issue
So how to update boot image safely without production down time?
