bug #4926 :  Some users had a problem with the database migration of classifieds up to 003 with MSSQL. In order the migration works, they had have to split the migration step 003 into two separates ones: 003 (that updates the SQL tables for the classifieds component) and 004 (to migrate the classifieds data into the JCR). This change cannot be reported into the classifieds source, so, for they can profit of a possible next database migration of classifieds, a virtual migration step is introduced: 004/up003; with this virtual step, the next concrete database migration of classifieds will be step 005.
