Enhanced Migrations Plugin + Rails 2.1+

In 2.1+ there are new migration style - it uses time stamp to create migration filename , just like Enhanced Migrations Plugin did.

Recently i updated my application to 2.1.2 (from 2.0.2) and found incompatibility with this plugin.

So we need to update our database!
We need take all Enhanced Migrations Plugin "migrations_info" and simply put them on schema_migration table !

First, backup your database.


DROP TABLE IF EXISTS schema_migrations;
CREATE TABLE schema_migrations (
version varchar(255) NOT NULL,
UNIQUE KEY unique_schema_migrations (version)
INSERT INTO schema_migrations (SELECT ID FROM migrations_info);
DROP TABLE migrations_info;

Now remove Enhanced Migrations Plugin from vendor/plugins,

And you're ready !
