Before that take a backup of your current data.

Dump of all databases

Code:

# mysqldump \
  -uroot \
  --password='your_password' \
  -hlocalhost \
  --all-databases \
  --opt \
  --allow-keywords \
  --flush-logs \
  --hex-blob \
  --master-data \
  --max_allowed_packet=16M \
  --quote-names \
  --result-file=BACKUP_MYSQL_4.0.SQL

Now a file named BACKUP_MYSQL_4.0.SQL should exist, which can be used later to recreate your data. The data is described in the MySQL dialect of SQL, the Structured Query Language.
