Hi Muggers

Can anyone tell me which is the best way to upgrade to tiger. Im using a G5 dual 2ghz machine with 10.3.8. I checked the apple website and they dont actually say which of the three ways works the best. Does it matter?

I dont want to lose all my info in mail, internet and cable connection so am not into a complete install. Im wondering whether to do a 'simple upgrade' or an 'archive and install'. I assume after the install I run the 10.4.2 updater?

Anyone with some advice from experience?

kind regards

chris
