How do I transfer Aperature library to a new computer and upgraded Aperature?

Assuming you have a Managed Library:

To move an Aperture Library to a new machine:

Link the two Macs together: there are several ways to do this: Wireless Network,Firewire Target Disk Mode, Ethernet, or even just copy the Library to an external HD and then on to the new machine...

But however you do choose to link the two machines...

Simply copy the Library from the Pictures Folder on the old Machine to the Pictures Folder on the new Machine.

Then launch Aperture. That's it.

This moves photos, events, albums, books, keywords, slideshows and everything else.

Dick, in addition to the Terence Devlin's post, you may want to rebuild your Aperture library in Aperture 2.1.4, before transferring it to the new computer. This is recommended in the Aperture 3.5.1: Release notes

A note on upgrading your Aperture library

If you are upgrading your Aperture library from an earlier version of Aperture, here are some guidelines to assist you in a successful move to Aperture 3:

• Before upgrading, it is recommended (though not required) that you perform a rebuild of your Aperture library. To rebuild an Aperture library, hold down the Option and Command keys while opening your library in Aperture 1.5 or 2, then click the Rebuild Now button.
• Aperture temporarily uses extra space on your hard drive during the upgrade process. This is for the purpose of backing up critical library info and insuring the integrity of your data during upgrade. If you don't have adequate space on your hard drive to accommodate the upgrade, Aperture will display a warning dialog. You may need to move your library to a different hard drive with more space in order to upgrade it, and then move it back to the original drive when the upgrade is complete. Any space used by Aperture during the upgrade is released and made available to you again once the upgrade has finished.
• Keep in mind that fully upgrading a very large library is a one-time process that can take a long time; the process may take many hours or even overnight, depending on the size of the library. Once the initial database upgrade is complete, you can begin working with your Aperture library. However, post-upgrade processing will continue in the background for some time, as face detection and preview generation are performed. (A progress indicator and the word "Processing" will appear in the status line of the Viewer or Browser to indicate these operations are underway.) While you can work with Aperture while these operations are performed, you may experience temporary slow-downs. Optimal performance will return when all post-upgrade processing is complete.

I had Aperture 2.0 factory loaded on my old Macbook 17, and I upgraded to 3.0 with a purchased disc. My old drive crashed and was unrecoverable. I have 3.0 upgrade disc, but the install manager asks for original serial number, which I no longer have. How can I install the program using the 3.0 Upgrade disc?

Thanks.

BTW: I am trying to reload in order to recover and merge my corrupted iPhoto libraries.

If Aperture 3 is an upgrade, you will need both serial numbers, for Aperture 2 and Aperture 3.

If you have a "Proof of Purchase" you can ask for a replacement serial number.

See: Pro Application Replacement Serial Numbers

Had you already upgraded to Mavericks and Aperture 3.5.1? Then you can download it from the App Store. This upgrade changes the licence to an AppStore licence.
