I'm hoping one (some) of the more knowledgeable posters here can answer my concerns about a specific issue I have. I am on OS Lion and have been debating updating to Mavs. What scares me is the issues with the new Pages 5.0. The wife and I have a small business totally dependent on documents we created in Pages 09, 4.3. Lots of work put into them that we just can't lose, and I don't want to re-do, especially with 5.0's limited feature set (compared to 4.3)! I've read here and there that Pages 4.3 remains on the system after upgrading to Pages 5.0. But I'm unsure if that is true when upgrading the OS from Lion to Mavericks. My questions then are: Will Pages 4.3 remain on my system after upgrading to Mavericks?? And: Is it possible to remove (or otherwise disable) Pages 5.0 to ensure that Pages 4.3 remains my default Pages app?? Thanks for any concise answers!
