The mysql server online is of version 4.1, which doesn't support row-based binary log. Nevertheless, I need the row-based binlog. Can I use the binlog generated by old mysql and import it into another mysql of higher version that supports row-base binlog to get the row-based binlog?
You cannot convert a binlog to another version, but you import its SQL as long as have mysqlbinlog for version 4.1.
Simply do the following:
- Run MySQL 4.1 version of mysqlbinlog against the MySQL 4.1 binlog, saving output to stmts.sql
- Install MySQL 5.x with these in
- Login to MySQL 5.1 and run
SHOW BINARY LOGS;
When done, the binlogs you see should be row-based.
Give it a Try !!!
Why can't you just convert ? The BINLOG Magic Number gets displaced with later versions.

Every time you restart mysql, the next empty binlog is created. Each version of MySQL has a different size:
- MySQL 5.6 : 120
- MySQL 5.5 : 107
- MySQL 5.1 : 106
- MySQL 5.0 : 98
In light of this, generating binlogs from scratch is the best way to go.
UPDATE : Thanks to Michael's Comment, you have to preload the data the binlog came from into the MySQL 5.1 Instance.
