MySQL手册版本 5.0.20-MySQL同步(三)
6.5 不同MySQL版本之间的同步兼容性
最早的二进制格式是在MySQL 3.23中开发出来的。在MySQL 4.0中改进了，MySQL
5.0又改进了。在配置同步时需要升级服务器的话，它们之间的因果关系在"6.6 Upgrading a Replication Setup"中描述了。
如果只关心同步，任何MySQL 4.1.x版本和MySQL
4.0.x是一样的，因为它们都使用相同格式的二进制日志。所以，这些版本是互相兼容的，它们之间可以无缝地运行同步。一个例外的情况是，MySQL
4.0.0到4.0.2由于开发的较早，无法和后来的版本互相兼容，所以不要使用它们(它们是4.0版本的alpha系列。它们之间的兼容性在发布包的手册中均有相关文档)。
下表展示了不同版本的MySQL之间的master/slave同步兼容性。
