HOW to Migration Cups 1.2 -> 1.3

[robert]

Hello,
I have a problem when I want migrate my RHEL server
Before, I have a server with REHL5 and cups 1.2 and now I want remplace it by an another server with REHEL5.3 ans cups 1.3.

But, I don't know how can I recover the old configuration of each printer.

I have copy and modify these files :
/etc/cups/cupsd.conf
/etc/cups/printers.conf
/etc/cups/ppd/*
/etc/samba/drivers/

But, I can see the share printers and they don't have their configuration ...

Have you an idea ?
Is there a procedure to migrate Cups 1.2 to cups 1.3
thanks and sorry for my english
