Upgrade from Tiger to Lion?

Hi,

I'm still using Tiger. Will I be able to upgrade directly to Lion when it is released or should I go through Leopard or Snow Leopard first?

Thanks,
Katie

Even if a Tiger to Lion upgrade is supported I wouldn't do it. The best approach IMHO is to back up your Tiger data and then do a clean install of Lion. I would clone the Tiger system to an external firewire connected drive. Verify that the external drive is bootable. If that works then do an erase and install of Lion. You can then copy your data from the external drive to the new installation on the internal drive.
Keep the external drive unmodified until you are absolutely certain that you didn't miss anything.

Thanks for the replies. As you may have guessed I am not that up to speed on this subject.

I do have a WD external hard drive connected via firewire. I believe it is 1 Terabyte. I don't know if it is bootable. Hmm, I'll probably really mess things up if I try your suggestion.

Thanks, though.

Based on what I've heard/seen, you'll only be able to download Lion from Apple's App Store. ...

Not quite entirely true. They will be shipping it pre-installed on new Macs... 🙂


Other than gettng a new machine with it pre-installed, I have also read that it will only be available via the Mac App Store. I don't know if there will be a way to download it on a Snow Leopard or Lion machine and then copy it to another computer for installation though. I'm not sure I would want an OS that doesn't provide me wth a way to install it if my HD goes south. I can put in a replacement drive, but then how do I get an OS on it if it requires an OS to get to the downlaod of the new OS? They almost have to provide some way to handle that situation.

I'd make a copy of the disk image prior to installation, and keep that for a backup. I can't imagine one would download it and have it autoinstall; you'd want to back things up first (which you should be doing anyway).


Besides...autoinstalling anything from the web is a bad idea....

Sure, but you have to purchase Lion before the installation and it cannot be done by using Tiger (no App Store).

I can imagine that some people will download some torrent version of Snow Leopard and than purchase Lion.


It is strange that Apple limits customers with older systems to buy the newest. I still believe that they see these discussions and will come with a solution. Maybee they have problem with upgrade Tiger to Lion, and forced clean-installation is shameful 🙂

No need to guess or speculate (Which is a no-no here) on this. It isn't too strange that Apple wants customers with older systems to buy newer ones. That's called capitalism, and advancing technology. After all...even Windows 98 or XP isn't supported any more. 😉

Speculating on how Lion will dowload and install is not productive and may be in violation of the Terms of Use of these forums. More information will be coming before long. We just need to wait.


Cornelius--


Not trying to speculate on Apple's part; I know better. I'm just saying what I might do when the time comes. You are quite right: we don't know how this is going to work out. (Wish we had some details....)


However...I still say one needs to watch anything that autoinstalls. Too many years of issues with Windows. Mine is a mixed marriage: I'm a Mac...my wife's a PC. You wouldn't believe what I have to fix/update on her unit...well...then again, maybe you would. 😉

I wish I could tell you one way or the other. I do think that we can be sure that there will be even more Apple magic, judging from the video of the presentation I watched. I was not sure if I wanted to upgrade from Sno, but now...

Yes, and no.

As long as your hardware requirements meet the minimum requirements, then it is definitely possible.

However, the way Lion installs is through the Mac App Store, which requires 10.6.6.

Because of this, you will need a friend or relative who has a Mac that is running at least 10.6.6.

What you need is an external HD that you can create a recovery partition with.

Once you create the recovery partition, you can download Lion onto that partition and boot your Tiger Mac from that external HD using target disk mode and install it.

Boom, you've got Lion.

Kind of a hairy work around, but its the only way to do it.

OR you can take it to your local Apple Store 🙂
