MySQL Data
Mac OS X Server version 10.2.8 preinstalled version 3.23 of MySQL. Server version 10.4
preinstalls MySQL version 4.0.20.
To migrate your MySQL databases from one computer to another, you can use the
mysqldump command from a Terminal window. To back up the data, type:
mysqldump -p table > backup-file.sql
or
mysqldump --opt database > backup-file.sql
Additional instructions for database backup and restore can be found in the MySQL
documentation at www.mysql.com.
Mail Database
Save the mail database if you want to reuse it. Its default location is /Library/
AppleMailServer/.
Webmail Data
If you’ve been using the SquirrelMail installed when you installed version 10.2 and want
to continue using it after migration, make copies of the address books and preferences
stored in /var/db/squirrelmail/data/.
