LPS-34265 We should avoid using *Service* in Upgrade. Suppose 6_3_0 adds a column to the Company table. It does so via an alter table statement. At this point, in the 6_2_0 upgrade code, that column hasn't been added. But, the hibernate XML file assumes it's there  in portal-hbm.xml. So when it tries to do the select or update via *Service*, it'll choke. So we have to do it manually via SQL statements.
