I think it depends on whether or not we decide to use the same IPs for the
server or use new ones. If we aim for reusing the IPs, we'd have to prepare
the new server for taking over and then let Hetzner physically replace the
servers, so the actual migration would be a single action.
Alternatively, we could use new IPs and then just set up everything on the
new server (host OS plus VMs) until it works. The final step would then be to
migrate the VMs individually (shutdown on baron, change DNS entry, sync VM
disk to new server, start VM on new server).

No, throughout the whole of 2012, we used no more than 6 TB of traffic, so 10
TB/month should be good enough for quite some time.

Yep, using additional IPv4 addresses would be pretty expensive, as we'd have
to buy the "flexi-pack" (for 15 EUR/momth) plus a /29 or /28 IPv4 subnet (for
8 or 16 EUR/month).
To avoid those 23 EUR/month, I'd like to use IPv6 for direct access to the
new VMs and use a reverse-proxy on baron for http traffic to/from the VMs.
Unless I'm mistaken, that should be good enough for things like buildbots.
cheers,
Oliver
