Migrating to Leopard

Right now I have Tiger Server running on a G4/933. We got a new (Intel) iMac, which frees up my G5/2ghz DP to become the new Server machine. Absent any conflicting advice, my approach would be to (a) move the current G4 server installation to the G5 via a diskcopy, then (b) do an upgrade from Tiger Server to Leopard. 1. Has anyone done a Tiger G4->G5 move via a diskcopy? Any problems? (Considering that I'm doing an immediate upgrade to Leopard, I won't be bothered by the lack of support for G5/64 bits in the Tiger installation.) 2. What experiences have people had with G5 upgrade (versus archive-and-install) from Tiger Server to Leopard Server. 3. Is anyone doing a Leopard Server book? thanks in advance, as always dave
