To import an iWork ’09 document, choose File > Open. Then, select the document and click Open. Or, you can drop the document on the Pages, Numbers, or Keynote icon in the Dock.

The first time you open an iWork ’09 document in one of the new iWork for Mac apps, you will see a dialog. This dialog lets you know that saving or editing the document requires you to use the latest version of the app on iOS 7 if you want to work with the document on iOS after using it on your Mac. 

When you open an iWork '09 document, you might see a list of features in your document that are supported in iWork ’09 but not in the new iWork for Mac apps.

• If you click Cancel, your document will close and the iWork ’09 features will be preserved.
• If you click OK, your document will open and you’ll be able to see what the document looks like without the iWork ’09 features. You’ll still be able to revert to the iWork ’09 version if you close the document without saving or by reverting from the File menu.

The first time you save or edit an iWork ’09 document in one of the new iWork for Mac apps, a dialog will ask you to confirm that you want to convert the document to the new iWork file format.

• Clicking Upgrade converts the document to the new format.
• Clicking Cancel cancels the save or edit.
• Clicking Edit a Copy converts a copy of the document to the new format while preserving the original in the iWork ’09 format.

Reverting your document to a previous version

If you have already upgraded your document to the new iWork file format and would like to revert back to a version of the document that you can open in iWork '09, do one of the following:

• You can revert to the most recent iWork '09 version by selecting File > Revert To.
• If you edited the document and want to preserve the edits, you can save the file as an iWork ’09 document by choosing File > Export To. Then, choose Pages ’09, Numbers ’09, or Keynote ’09.
