what do you get when you run:
select * from system_property where name = database version?
if you do a 'blasadmin -s default show data all' are you connecting to the right database ?
(use your appserver instance name if it's not default)
Ok thanks Bill.
I can now see that the connection strings are very subtly different between _template and default deployments.
So an old DEV DB was migrated.
I'll modify the _template deployments connection string and re-run the migration.
