## What's a "Database Schema Update"?

Obviously you installed a newer version of JaM, which is always a good idea. Sometimes new versions of JaM need updated database objects, e.g. new columns or new tables or something similar.

JaM detected that you use a newer version of JaM with an older version of the database objects. JaM automatically can update your database schema. Although JaM is very carefully in updating your data it can happen, that the update procedure fails, possibly damaging your data.

So you may want to make an update of your JaM database before proceeding. Use the following command to make a full backup of a MySQL database:

      mysqldump -q -u username -p password \\
                database_name > backup.sql
