Package Manager - package does not include all content

[achink]

The content author team created few pages which we need to port from one CQ instance to another. I opened up package manager on source and added all of 30 pages as individual filter and build / download.

On target instance, opened package manager and uploaded the ZIp and installed. When i verified few pages within target instance, thee component/content does not copied over completely.

What could be the reason? Any suggestions or pointers are welcome.

A couple troubleshooting suggestions:

1. How are you checking for the content - are you looking in CRXDE Lite, or just looking at the page in author. You want to look at the actual nodes in CRXDE Lite to verify that the problem is actually missing content and not a display issue with your components or templates. 
2. If the content is actually missing in CRXDE Lite then check you error logs from the time of the install. There should be a listing of every node in the package and a status - ocassionally on package install there will be an error related to a particular node, in which case only that content will be missing. If you see an E next to a node that indicates some kind of error on the install. There will usually be a stack trace in error.log indicating source of the problem. 
3. If the content is in CRXDE Lite but not showing up on your pages then that would indicate some either error in your component code, or perhaps missing code (if your source and target environments aren't on the same release). Looking at error.log after you load the page will probably point you in the right direction in this case.
