Hi Peasant,
I understand where you are comming from on this, but for relocating/moving/virtualising systems there are much more appropriate ways of doing it! On this job I've personally relocated more than 100 servers, the previous job it was almost 1000 as part of a team. The only outage suffered was on the legacy equipment that had to move data centres (lift and shift).
My preferred tools are TDMF and DRBD, both of which allow move/relocate function without any significant outages. Using LVM mirroring does make things easier in this context, but trying to mirror a multi Tb Oracle DB accross a WAN is problematic and in my experience custom tools do a better job.
Regards
Dave
