I manage a server that currently runs Debian/Etch, and Xen 3.0. Each virtual machine is also running Debian/Etch.
Lenny is the next release of Debian, and includes Xen 3.2. Unfortunately, I believe there is no automatic upgrade path (via dist-upgrade) between Xen 3.0 and Xen 3.2. (Xen 3.0 is listed as an obsolete package in the lenny release notes).
What steps should I follow to end up with the server running lenny/xen3.2 and the virtual machines running lenny?

I was able to migrate a Debian Etch/Xen 3.0 server to Lenny/Xen 3.2 using dist-upgrade. All apt-get did was download the appropriate packages and install them. After making sure the grub config is correct and will be booting 3.2 all of my paravirtual machines booted up. All of the PV machines are Gentoo so I can't comment on the client upgrade for Debian but it shouldn't be that difficult. I did have some issues with an HVM machine and had to rebuild it.
