Migration Runners

There are multiple different ways to execute migrations using the runners. The simplest and most straight forward is from the command line using the migrate.exe tool.

Command Line Runner

For a full listing of options simply run migrate.exe from the command line by itself or check the Command Line Runner Options.

Migrate.exe /connection "Data Source=db\db.sqlite;Version=3;" /db sqlite /target your.migrations.dll

NAnt Runner

See Nant Runner Options for a complete list of options.
