The keep the analysis files, editing the collection's sql won't help, as the analysis file paths aren't kept in it.
I agree a whole collection export/import is needed, and will surely be added in a future major release.
What you can do now, as a workaround, is export/import playlist using "Export as DJ Bundle". The bundle will contain a copy of the tracks and their corresponding analysis file. It isn't perfect though: you have to do it on a playlist basis, and it will loose the tracks files' directory structure, by putting all tracks in the same directory. But relocating after that import should keep the analysis as well.
Let me know if you have any issues.
