Upgrading sequence AOS, NCC, Foundation

Hi Team, I will be carrying out upgrades tonight at 8 pm GMT and want to plan before hand: can I please get urgent assistance: I understand that I can jump from AOS 5.15.6 LTS to 6.0.1.1 directly but before doing this I want to confirm below: The order I can see is to upgrade Foundation 1st: we currently have foundation-4.6.2-6e9b7fc8 version can we directly jump to 5.0.4 version of foundation? or we have to install from older base versions one by one to reach 5.0.4? NCC 2nd: we currently have 4.1.0 can we jump to 4.2.0.2 or we have to install 4.2.0.1 first?
