EF Migrations: Rollback last applied migration?
database-migration, entity-framework, entity-framework-4, entity-framework-migrations
Solution
As of EF 5.0, the approach you describe is the preferred way. So
`PM> Update-Database -TargetMigration:"NameOfSecondToLastMigration"`
or using your example migrations
`PM> Update-Database -TargetMigration:"CategoryIdIsLong"`
One solution would be to create a wrapper PS script that automates the steps above. Additionally, feel free to create a feature request for this, or better yet, take a shot at implementing it! https://github.com/dotnet/ef6
Problem
This looks like a really common task, but I can't find an easy way to do it. I want to undo the last applied migration. I would have expected a simple command, like ``` PM> Update-Database -TargetMigration:"-1" ``` Instead, all I can come up with is: ``` PM> Get-Migrations Retrieving migrations that have been applied to the target database. 201208012131302_Add-SystemCategory 201207311827468_CategoryIdIsLong 201207232247409_AutomaticMigration 201207211340509_AutomaticMigration 201207200025294_InitialCreate PM> Update-Database -TargetMigration:"CategoryIdIsLong" ``` (At least I can use just the name, skipping the timestamp...) Is there an easier way?
