Back up all of your older Pages ’08/’09 .pages/rtf documents to external media for safe keeping.
If your documents were all created in Pages ’08, then they are safe because no current version of Pages on IOS(v2.2.1), OS X (Pages v5(.2)), or Pages for iCloud beta can open them. RTF is no longer supported in any current Pages application. You would have to export to MS Word .doc to interchange the Pages ‘08 content with the current Pages applications. Pages ’09 can also open older Pages ’08 documents, and RTF files.
The installation of Pages v5(.2) on your Mac would have moved the existing Pages application into /Applications/iWork ’08/’09 depending on which Pages release. The older Pages continues to work on Mavericks, providing you do not double-click Pages documents to open them, as Pages v5(.2) will launch, and automatically convert them to the new document format.
The latest IOS Pages v2.2.1, Pages for iCloud beta, and OS X Pages v5(.2) all use a new, backwards incompatible document format — one that still uses the .pages file extension. Pages v5(.2) on OS X is a brand new application that is missing about 100 features/functionality that was available in Pages ’09 v4.3. Consequently, Pages ’09 document functionality is a superset to Pages v5(.2), and templates and documents may have functionality filtered from them when opened by Pages v5(.2). It may do so quietly with truly annoying results. Pages v5(.2) has an export to Pages ’09 feature. What you export may not be what you expect.
