Thanks Raj!

If I also wanted to migrate the passwords , the CSVDE file does not
contain that info if I am not mistaken, but LDIFDE does - could I then run
a LDIFDE import, and if so, which fields would I need to import in LDIFDE
just to update the password and nothing else?

Or would it be better to skip CSVDE, and just use LDIFDE and import the
fields you listed plus the field that contains the password info (I have
not been able to identify the exact LDIFDE field that contains the
password.

Best regards
Mike
