Import records can copy the data from a table in your old table to a table in your new file. Do this once for each table and you have copied over your data. This can be set up as a single script so that you just run the script and the data is all copied over from all tables.
But if you have any auto-entered serial number files, their next serial value settings will need to be updated to be at least one number greater than that of the largest value just imported. This also can be scripted.
And it's possible to set up your database so that many updates can be deployed without any importing of records if you use the Convert to Seperation Model.
