[SOLVED] Failure in upgrade from 4 to 5

[jerry]

I've just failed (mea culpa) in upgrading from 4.4-1 to 5.2. I followed the instruction from the wiki, however I missed one important (as it turned out to be very important later) of the preconditions - correct repository configuration.
I didn't use enterprise repository and also no-subsrciption repository, so I updated only Debian Jessie packages after executing "apt-get update && apt-get dist-upgrade" commands. After reboot I had only three commands from pve family: pvecm pvesm pveum.
I could not login to GUI, but the "pvecm status" command returned correct information:

root@pve3:~# pvecm status

I decided to add no-subscription repository to the /etc/apt/sources.list file:

# PVE pve-no-subscription repository provided by proxmox.com,
# NOT recommended for production use
deb http://download.proxmox.com/debian/pve stretch pve-no-subscription

but there was nothing to update or install.
Finally I decided to set up install repository and update repository key:

echo "deb http://download.proxmox.com/debian/pve stretch pve-no-subscription" > /etc/apt/sources.list.d/pve-install-repo.list
wget http://download.proxmox.com/debian/proxmox-ve-release-5.x.gpg -O /etc/apt/trusted.gpg.d/proxmox-ve-release-5.x.gpg

I successfully updated (rather installed) system by running "apt-get update && apt-get dist-upgrade" commands.
After restart everything seems to be OK - node is visible and operable. Although the goal has been achieved, I wonder if something has been missed?
Could I ask Proxmox support team for confirmation of this method?

When you try to install the package 'proxmox-ve' and nothing comes up, then it's good.
