Sean,

Many thanks for such a quick fix, the migrage worked first time.

Will I need to use subversion when updating on railsmachine, or can I  
simply update the gem and restore from the migrated datebase on my local  
machine?

Thanks again

Sharon

The turnaround for releasing gems is obviously longer than single  
updates via Subversion. I don’t think you’ll have to worry about SVN on  
RailsMachine, they fully support it. Just make sure to run rake  
radiant:freeze:edge before you try to migrate.

That said, you could use the experimental import\_export extension if you  
want. Unfortunately, it’s so new I can’t guarantee it will work with  
all DB configurations.
