OS Update: Etch to Lenny on ISPCP Host?

[lbm]

Hi all,

is there any experience updating the underlying Debian OS from "4.0 etch" to "5.0 lenny" on an ISPCP host? By the way, I am running ISPCP 1.0.2 and (which might cause issues) Maia Mailguard 1.0.2a.

If so, I'd love to hear if this is (easily) possible or if its recommended to set up another ISPCP host with lenny and migrate the data to the new system [1].

Thanks,
Thorsten
