We're running 30+ SilverStripe sites on a server for multiple clients. Currently testing 2.3.0-rc1 in the work to be prepared for the new release. Is there a way to script the db/build?flush=1 call to migrate the database by wget? We do not know any administrator logins for the sites because we just providing the infrastructure. When we upgrade to SilverStripe 2.3.0 we will do that centrally for all site/clients and we would like to migrate the databases by batch/script without knowing any administrator login for the CMS?
