  Otherwise, I can't see why you would need to collect stats after adding new nodes - stats are about the table, the no of rows on your tables will stay the same,as well uniqueness ratio etc - so don't see need to recollect.  


What other operations do any of you perform after an upgrade?


Thanks...
