On an internal Test 10gR2 Database running of CSALTER.plb is Failing
when Attempting to Alter Character Set from US7ASCII to AL32UTF8.

Qs Does User/Application Data which during CSSCAN reported 2 types of
Errors i.e. "Truncation" & "Lossy conversion" necessarily needs to be
Manually Corrected?

NOTE - We do NOT seek to Manually correct the Application Data, but want
CSALTER to go thru successfully.

Qs Should the 3 indexes which need to be RE-built be DROPPED before
Running the CSALTER.PLB Script & RE-built After ALTERATION?

Application = Banking Product

O.S. = HP-UX B.11.11

Thanks indeed
