Normally, the Mac App Store should detect Aperture, so you may have to delete it before being able to purchase Aperture. However, you can try it without deleting Aperture first and see if you can purchase it.
Make a backup of the library before opening Aperture 3 for the first time. It's possible that the Aperture library may be upgraded to be able to use it with Aperture 3, the most recent Aperture version
Before buying 3 run 2 and do a repair on all your libraries. Once you install 3 the libraries will be upgraded and will no longer be accessible from 2 so you want to make sure they are in good shape.
Then make backups of all the libraries. The upgrade of the libraries usually goes OK but things can happen so make sure they are backed up.
Now move Aperture from the system Applications folder to the Trash but don't empty the trash. Connect to the Mac App Store and purchase Aperture.
Once the install is done start Aperture by holding down the option key. This will bring up a window that allows you to select a library or create a new one. Create a new library and let Aperture start. Make sure all the basic stuff i working. Import a few images and play around a bit.
Once you are sure that Aperture is working OK, quit it and locate one of the old libraries in the Finder. Double click it and Aperture should start with a message telling you the library needs to be upgraded, upgrade.
This might take a while depending on the size of the library. If you have multiple libraries I suggest starting with a smaller one first. Let the upgrade run do not force quit Aperture. If you have repaired the libraries with 2 before doing this you should not have any problems.
good luck post back if you have any questions.
Just some remarks in addition to the Upgrade procedure outlined by mende1:
- Keep Aperture 2, don't delete it. Just rename it and move it to a different folder. You may need it, if something happens, when upgrading the library, or when you come across older vaults, that refuse to open in Aperture 3.
- Upgrade all plug-ins to the latest versions. Some may no longer be compatible with Aperture 3.4.5
- And make sure that your Aperture library is in perfect shape, before you upgrade to Aperture 3. The upgrade will need to upgrade the library, and that will be a major reconstruction. Run the Aperture Library First Aid Tools, to repair the permissions and the library, while you still have Aperture 2.
To repair or rebuild your Aperture library
- Close Aperture, if it’s open.
- Locate the Aperture library you want to fix, then hold down the Command and Option keys while double-clicking the Aperture library.
- The Aperture Library First Aid dialog appears. Select the Repair option you want to use - first "permissions", then "database".
Have a look at the Aperture Release Notes:
Scroll down to the bottom of the document, where it says ,
A note on upgrading your Aperture library
Added: Just saw that I overlooked that part of the question:
? Will this affect my photo libraries? Any direction is highly appreciated.
Installing the new Aperture version will upgrade the library to a totally different format, once you open your library in Aperture 3.4.5.
If you have other Macs, that cannot be upgraded to run Aperture 3.4.5, you will no longer be able to open your Aperture libraries on those macs.
Backing up the Aperture versions of the libraries together with your Aperture 2 application is essential to be able to fall back, if something should go wrong - it usually does not go wrong, however.
Now I see, Frank Cagiano explained all that already
how can I keep a backup of the libraries together with Aperture 2
How are you keeping backups of your system and your Aperture libraries up to now?
Do you still have Aperture and your libraries on your PowerPC? That is a good starting point for a backup. The second would be your regular backup of your system and user data, for example a TimeMachine backup, if it containns the disk that hold your aperture libraries and original image files.
In addition, it would be very useful to copy your Aperture library to an external drive, and the Aperture application to. simply drag and drop from the Finder. To copy the Aperture application from the Applications folder, hold down the alt/opt key while you drag it. Otherwise you'll only create an alis.
I'm back; I was having a walk with my dog while I was backing my Aoerture libraaries too an external HD. I already have Aperture 2 in my new iMac fully functional (I hope) because I migrated all the stuff from the old Mac from the TimeMachine backup.
The problem I have now is that I tried to open Aprtr. 2 and is asking for the serial number. I cannot find the installer DVD or the packing. How can I find the Serial number?
In the old machine I open Aperture and clicked on "About Aperture" and copy in a paper the serial that the window showed; when I put that number in the new Mac the serial was rejected. Did I do something wrong/ What can I do?
