Hello, I'm running OS X 10.5.8 on my Intel Core 2 Duo MacBook. Is it possible to upgrade from this version of the OS straight to the new Lion version?

According to this page, one needs the latest version of Snow Leopard to upgrade to Lion:
Apple - OS X Lion - Get Lion in July. Only from the Mac App Store.

Is this the only way to go?

Thanks!

Yep, you'll need to install SL first.
Mac OS X 10.6 Snow Leopard - Apple Store (U.S.)

All right, thanks. I have quite a number of applications and programs (and files, of course) installed on this version of the OS. I bought this Mac in January 2008 and have only upgraded to newer releases of the same version through the Software Update. Could you recommend a resource that outlines how to upgrade from OS 10.x.x to Snow Leopard in the safest way possible?

Thank you!

The runs automatically once you insert the disc and click the installer, keeping everything in tact.
Even if you're not upgrading, you should have an external HD with time machine backups, and preferably a clone like Carbon Copy Cloner.
Carbon Copy Cloner - Home
You should check to see if there is any software that you have that is not compatible with Snow Leopard, although most developers are up to speed.

I am using Time Machine for regular backups, although without Carbon Copy Cloner. I've read another thread on upgrading the OS (erase and install vs upgrade-install), where one user recommended SuperDuper:

Upgrading to 10.6 snow leopard from 10.5...

I'm not sure which disk copier is the best, but I'd like to do an erase and install (seems the more thorough option), so it looks like I will be choosing between one of the above.

Either of those will work nicely. The paid version of SuperDuper has a few features that seem to either not be available or not be as easily implemented in Carbon Copy Cloner.

You can also use Apple's Disk Utility program to clone your drive. The problem with Disk Utility is that each time you clone a drive it's "all or nothing" whereas the other programs can perform incremental clones one the initial one is completed.

All right guys, thank you both for help! The road ahead is clear.
