Could someone advice me on upgrade process for a set of 515E PIXes firwall code and pdm version upgrades.
I will be upgrading a set of pixes in a failover configuration, I have read the upgrade process for failover firewalls and seems fearly straight forward but my question is, would it be feasable when tftping the new version to also tftp the pdm image file upgrade as well, is this something that can be done all together in one process or would it be best to upgrade the code one at a time, that is firewall code first and got through the boot/failover process and tftp the PDM image on another install process.
PIX Models PIX515E
64 RAM, FLASH 16MB
Version 6.2.1 ( Upgrating to 6.3.5)
pdm ver 2.0.2 ( upgrading to 3.0.4)
