Migration from Debian/powerpc to Debian/i386

[Eduardo Trápani <eduardo@esperanto.org.uy>]

Hi,

I'm currently using Debian on an iMac G5. Everything is alright but I 
have to hand the computer over to another user and I will get a PC in 
return.

I'm not sure what would be the best path to follow to recreate my debian 
environment in the new machine.  I cannot repackage packages because the 
architecture is different,but maybe there is an automatic tool to save 
the configuration and the list of packages.

On top of that, I don't know if things like MySQL databases can be 
simply copied or if I should export/import them.  Is there a way to know 
if a package data is platform independent?  (little/big endian issues 
and things like that).

Thanks, Eduardo.
