What to do with old configs

[Alexander GQ Gerasiov <gq@cs.msu.su>]

Hi there.

I create package A version 1.
It provides config file /etc/A/X.
In version 2 there are no more /etc/A/X.
If version 2 see /etc/A/X it will work wrong.
But usual from A=1 to A=2 upgrade will leave /etc/A/X.
What can I do in such situation? Can I remove /etc/A/X in preinst of
version 2?
