Re: Migrate running IA32 system to Debian AMD 64?

[Dean Hamstead <dean@bong.com.au>]

you could change to a 64bit kernel i believe but as for swapping out all 
your software in 5 mins...

chances are youll muck something up. so from a system admins point of 
view i would seriously advise you to get another machine, set it up,
copy your data across. then when you are happy, swap that machine out
as the live machine.

i just dont think a 5 minute downtime would be at all possible.
