The version column of migrations table is to small to a version number.

[yesmeck]

I'm using Doctrine DBAL and MySql, and it creates a migrations table.But the version column int (10) is too small to a version number. When a version number like 20120628200012 insert into migrations table，MySql will convert it to 4294967295.
After I change the version column type to bigint, It works fine.
