Updating all Pages documents

I would NOT update them. I would use them in the Pages version they where created because ages 5 will mess up quite a few of you documents depending on which features you have used in Pages 09 that Pages 5 doesn't have. Use Pages 5 for your new documents only. I hope you are aware of that Pages 0n is still on your computer if you haven't deleted it. Look in Applications/iWork 09 folder. Pages 5 is in Applications.

You are aware that Apple removed over 100 features from Pages 5 and that it alters/damages older files that it opens?
