My sympathies. I am going through a similar situation with Dell (though we are getting rid of Tivoli for SMS).

But if someone tells you that the Tivoli client and the SMS agent can coexist nicely on a system, don't believe them. A few years ago, we tried to use Tivoli to remove SMS. Our Microsoft TAM and a rep from IBM both told us there should be no problem. The results were not pretty. Dozens of hung systems and desktop visits ensued. Oops!
