There is only one problem with the approach of essentially re-creating
the database as I do periodically with the data that Jim so generously
provides - and that is any studies I have created are lost, as I believe
these are stored in the same files as the data is. It would be nice to
have a migration tool to copy them over from the old database files.
Alternatively, it probably wouldn't be too big a deal to write a utility
program that compares the old database files with the new ones and just
adds/deletes the changes to the existing database rather than doing a
complete change-over. A project for when I have a little more time.
