Subject Re: Moving from 0.7.0-beta1 to nightly build
Date Wed, 22 Sep 2010 14:56:12 GMT

Sorry Jonathan, not quite getting you

I'd gathered the strategy is stored in the schema.  However I'm not quite
getting what you mean, "Install the new build before loading it"  Are you
saying I should load the new build on a clean machine and use schematool to
import the schema from the beta1 cluster ?
