Hello,
I would guess it is an issue with the format that the data is stored in, in the old column.
Is it always the same format e.g. mm/dd/yyyy? Can you post a sample of the data in the old column?

I think the problem is those 00000000 values. They aren't convertable to datetime.
Try this
update tablename set newcolumn=CAST(oldcolumn AS DATETIME) WHERE ISDATE(oldcolumn)=1

Hello,
Yes, "GilaMonster" is right. It is the zero filled values that cause the problem.
There is the question of what you want to do in the case of zeros? Do zeros represent a non existent value for the row? In this case you might want the new column to contain a Null.
