I have one table with a "missing index" e.g. the table has
Index 1
Index 2
Index 3

Index 5
Index 6

(No index 4).

The conversion Wizard throws error
ERROR 12298: Index number out of range Legal index numbers: 1, 2, 3, 4, 5, 6, 7, 8, 9. Attribute = DF_INDEX_SQL_PRIMARY_KEY, Table = MyTable (-2), Indexnumber = [4], Source = MSSQLDRV.Set_Attribute

Obviously the work around is to create Index.4 as a duplicate of the primary key, but it would be nice if the Wizard could handle this.
