Learning that I somehow installed the dreaded 4.5 P1, I am prepping for to move to 4.5 P5, then in a month or two, 4.6. I cannot find much on the upgrade path for this process. Do I need to go to patch 3 or higher first before patch 5 or can I go directly to P5? Also, is there any specific prep work on this upgrade? I have not seen any definitive information for this particular upgrade.
Thanks in advance
Should be ok. I did an upgrade around 6 months ago from that version to Patch 5.
It is a supported upgrade path - see https://kc.mcafee.com/corporate/index?page=content&id=PD23448 (scroll down to to the upgrade requirements).
