I got Joe Kissell's great e book on upgrading to Tiger, and unlike Panther, he recommends doing erase and install, and then using migration technology with a cloned HD from external HD.
So I'm not conversant with cloning the HD, and would probably try it with disk utility, etc. but the whole thing kind of worries/scares me to be quite honest.
I call up Apple to ask about this, get some confirmation, I have Apple care, and I talk to few people, and most of them don't have a clue or opinion on any of this.
What do most you think on this subject. thanks!

It's really really easy to do, I just did it a few days ago with Panther. Download Carbon Copy Cloner from MacUpdate. Use CCC to clone your HD to your external HD. CCC recommends that an external FW HD be erased and formatted before you do the clone. Boot up the clone and make sure everything is ok dokey. You could use "Restore" from Disk Utility, but CCC has such a strong track record you really can't go wrong with it.
Do the Erase and Install of Tiger on your internal HD. Once it's installed at some point you'll be asked if you want to transfer all your stuff from your "old mac". Turn on your external HD with your cloned old system and follow the prompts and the Setup Assistant will transfer everything over. I had to re-enter a few license codes for various shareware apps, but for the most part, it moved everything.
It's all fairly easy, just takes time......

Yes did it today, Strange that CCC is so much better than Apple DU.
I missed part about doing custom install, don't remember that being offered!

So why, in Tiger, is it better to do erase versus archive? I did archive from Jaguar to Panther, it was fabulous, everything worked just as before (settings etc) but faster and better. The erase and migrate seems a roundabout and slower way of doing things, so, again, what is different with Tiger??

A few things:
* Formatting erases the drive. This will also be a way of "defragmenting," as files when installed will not initially be fragmented. You shouldn't need to defragment with OS X, but still, it could be a bit faster when less fragmented.
* Archive & Install replaces the System folder ONLY. /Library isn't touched. Any cruft or startup items you have in Library will remain with an Archive & Install. With an erase install, they're gone, and you'll need to reinstall those particular apps (migration assistant may well pull them over, though). This will clean out crap cruft like haxies, that can cause stability issues.
