Trying to upgrade from 3.90 to 4.20 by running the 3.9 to 4.0 script, then 4.0 to 4.1, and then 4.1 to 4.2 script. The first two scripts run with out any errors but the 4.1 to 4.2 script fails with the following error:
(1 row affected)
Msg 5074, Level 16, State 1, Line 2657
The index 'idx_DCh_43_42_QueuedEmail' is dependent on column 'SentOnUtc'.
Msg 4922, Level 16, State 9, Line 2657
ALTER TABLE ALTER COLUMN SentOnUtc failed because one or more objects access this column.
Please help me figure out what I need to do to get it working.
