I have read all the upgrade documentation for PanOS 4.0.1 and its seems very clear on how to upgrade the units themselves. What I have not found is supported process for upgrading an environment that uses Panorama. We have Panorama and MANY 4000 series PA's running 3.1.5 code today. What would be the supported process/order for ugrading Panorama and the PA devices? Moreover, can I run 4.0.1 on Panorma and only some PA devices while other continue running 3.1.5 code? Thanks,
