USAGE
 yiic migrate [action] [parameter]
DESCRIPTION
 This command provides support for database migrations. The optional
 'action' parameter specifies which specific migration task to perform.
 It can take these values: up, down, to, create, history, new, mark.
 If the 'action' parameter is not given, it defaults to 'up'.
 Each action takes different parameters. Their usage can be found in
 the following examples.

EXAMPLES

* yiic migrate
Applies ALL new migrations. This is equivalent to 'yiic migrate to'.
* yiic migrate create create_user_table
Creates a new migration named 'create_user_table'.
* yiic migrate up 3
Applies the next 3 new migrations.
* yiic migrate down
Reverts the last applied migration.
* yiic migrate down 3
Reverts the last 3 applied migrations.
* yiic migrate to 101129_185401
Migrates up or down to version 101129_185401.
* yiic migrate mark 101129_185401
Modifies the migration history up or down to version 101129_185401.
No actual migration will be performed.
* yiic migrate history
Shows all previously applied migration information.
* yiic migrate history 10
Shows the last 10 applied migrations.
* yiic migrate new
