Etch -> Lenny -> Squeeze The Lenny -> Squeeze upgrade works fine, if you have a clean Lenny- installation. I.e. you first must upgrade to Lenny. >> >> Basic current configuration: >> - 2 vanilla Intel-based servers, 4 SATA drives each If you have Intel e100 NICs, then you will experience problems with the non-free firmware drivers.

I do not want to risk the problems Etch ----> Squeeze, even not on the development (used for programming and test) machines. Lenny to Squeeze was nearly without problems (Dom0 and DomU). DRBD 8.2 (since 8.3.2 api:88/proto:86-88) should work with the other node having DRBD 8.3.7 (api:88/proto:86-91) -- theoretically. BTW: If your hardware is as old as the software, then think about new hardware.
