Maybe you can do something like that: *Use openID APIs to log in your user (you can serve all Google Apps domains with a single app. This is no more tied to a single domain). See http://code.google.com/appengine/docs/java/users/overview.html#Authentication_Options and http://code.google.com/appengine/articles/openid.html for a guide.
*Keep the old version of the app for your existing customer, tied to their domain. All it requires is a double deploy (maybe with some minor tweaks to keep the openID stuff out of the old customer's version) for your application. If you want to migrate your old customer's data to the new app, you can also see if new tools for massive data migration (see announcement of high replication datastore) can do the job you need. Some time ago userIDs were stable across login options (google apps domain / openID) so it should not be hard to migrate everything.
