Will it work to un-install Snow Leopard (booting from original disks) and then reinstall, then upgrade without erasing hard drive on iMac?

I have both a bootable backup exernal hard drive and the original system disks.  I have read on these support pages that you cannot get snow leopard freshly installed without erasing the whole whole drive since the original installation disks are older than the current updated version. I have also read here that it is possible to get the system newly installed (though it's wise to have a back up of the rest of your files).  I need to know which can work.  Is there an un-install function after booting from a different source?   If I can get the system filess off the main hard drive and then install Snow Leopard from my original disks, then go through the upgrades, and end up with the rest of my files intact, that would be wonderful.  I have all the adobe design premium software on the system with their updates and would like to not spend hours and hours restoring it all.   And since I don't know where all the little bits and pieces of the Adobe programs get installed, perhaps it won't work anyway?




iMac, Mac OS X (10.6.8)
