I have created a custom table for my site called "rasoloComments". When developing locally I would get the following error:
-> System.InvalidOperationException: The migration plan does not support migrating from state "stage.rasolo.azurewebsites.net".
In order to get rid of the error you have to empty the row in the table of the database named "dbo.umbracoKeyValue" with the name of the database in the error message.
My query looked like this:
delete from dbo.umbracoKeyValue where [value] = 'stage.rasolo.azurewebsites.net'
