# MIGRATE MySQL4 DATABASES TO MySQL5 - Steps for dumping and converting
# 
# Uses mysqldump and patches output to be compatible with MySQL 5.5+ (? - no sure 
# at which specific release of MySQL 5 the old style syntax support ended).

# Use on own risk, always try with test databases first. No warranty at all!
