Panther to Tiger with a bootable Lacie external

[dnanian]

Without quoting, but in order:

- Yes, when you install Tiger, it'll ask where you want it to install, and you'll choose the main partition on the LaCie, and do a clean install.

- Tiger will automatically boot to the drive it installed to, so there's nothing to do. But, you can switch the startup drive in System Preferences, under "Startup Disk". You can also option boot...

- Since you've migrated, after you're satisfied you can erase-and-copy to the internal (or, if you'd like, do a Smart Update; the result's the same, but Smart Update might be faster).

- Finally: you've already created the partition for the Safety Clone, so once you're happy with Tiger and clone it to the internal, you then use SuperDuper! to create the Safety Clone and boot from it. You can select the drive to boot from, again, in System Preferences...

You're in control over what you're booting from...
