Am looking for some advice/tips/how-tos/whatever to help in a p2v migration I am about to undertake.

We have a machine in place that I would like to migrate, however am unsure as to what the best option would be. I am not going to get much time for the machine in question to be *not available*, so wondered if I could use rsync or similar to create a backup of the filesystem in question directly into a directory structure on the new server for the resultant Xen VM. I could do this whilst all things are still live. At the moment we'd like to swap over, we could then do a quick and final rsync, turn off the original server and bring the Xen VM up.

Does this make sense??? I presume there will be some directories and files that shouldn't be migrated (/dev, /tmp, etc) which files/dirs are safe to leave behind???

If you're not using udev, you'll want to migrate /dev over. /tmp is also fine.

I usually just exclude /proc and /sys.

The reason I'd like to move the server over, rather than install a new VM and update it, is because as mentioned its a software dev box and has been here a while, (before I arrived). Hence I am unsure as to what packages and apps have been installed and how.

Sounds quite reasonable to me. It's similar to how I do it..
