I'm building a solution for a client in kiosk mode. I'm going to be giving them an initial version and then update it based on suggestions. I'd like to move the data from one version to the next so that they don't lose it. Is the best way just to create an export and import script and export before i replace with the new version and import? It's 4 files worth of info.

An alternative is just to create an import script in your new version (one in each of the four files) that imports directly from the previous versions.

Before you drop the new versions in, you need to re-name the old ones (eg add 'OLD' to their names). Have your import scripts already configured to find files with their names changed in this way, in the current directory.

You can set the import script to run automatically the first time the files are opened, if you want it to be as easy as possible for your users.
