Issues upgrading proxmox 1.7

[webservio]

When tried to upgrade a production server from version 1.7 using the following link:
http://pve.proxmox.com/wiki/Downloads#Update_a_running_Proxmox_Virtual_Environment_to_1.9

Once I rebooted the system my network cards were not accessible so I had to revert from whatever the default boot was back to 1.7 or something that currently is working for now. Here is the information of the working environment:

pveversion -v
pve-manager: 1.7-10 (pve-manager/1.7/5323)
running kernel: 2.6.32-4-pve
proxmox-ve-2.6.32: 1.9-55+ovzfix-2
pve-kernel-2.6.32-4-pve: 2.6.32-30
pve-kernel-2.6.32-7-pve: 2.6.32-55+ovzfix-2
qemu-server: 1.1-28
pve-firmware: 1.0-10
libpve-storage-perl: 1.0-16
vncterm: 0.9-2
vzctl: 3.0.24-1pve4
vzdump: 1.2-10
vzprocps: 2.0.11-1dso2
vzquota: 3.0.11-1
pve-qemu-kvm: 0.13.0-3
ksm-control-daemon: 1.0-4



My question is what exactly are the choices of upgrade to 1.9? I tried a test upgrade from 1.xx to 2.xx and
did not work and got many error messages. In ways in my opinion upgrading from 1.xx to 2.0 is very risky. So in this case I wish to do the safest upgrade. So am I using the right documentation in th elink above? Does 1.7 upgrade directly to 1.9? Or do I need to upgrade to 1.8? Many thanks in advance.

upgrade to 1.9 (see also http://pve.proxmox.com/wiki/Installing_Proxmox_VE_v1.9_post_Lenny_retirement)

and the to latest 2.x, see http://pve.proxmox.com/wiki/Upgrade_from_1.9_to_2.0

but you can also backup your VMs and CT and, do a new installation and then restore. if you can have both systems, this is the safest way.
