12 iPad Pages (version 1.7.2 under ios 6.1) documents were backed up using iTunes(version 11 I believe) on iMac (under OS X 10.8). When ios 7 and compatible version 2 of Pages were installed the new Pages "library" shows 12 old documents. But any attempt to view one of these documents leads to an error message claiming something like "cannot import due to bad file format". I have identified several of the SQLite 3.x backup files as coming from specific Pages documents via terminal level "grep -i keyword *" in the most current backup directory. I am unfamiliar with SQLite nor do I have any specific knowledge of how iTunes encodes/compresses/encrypts its backup process. Are there known tools to let me view or recover the actual Pages document backed up in an SQLite file?
