It doesn't really complicate the upgrade. The only complication that seems to come in is if you're on a premier account. Then canceling the preorder can get tricky because the rep has to know to ask someone doing technical support on their end how to proceed in the system.
Once canceled, the upgrade reappears.
Also, I think OP mentioned not canceled until the 19th if they do decide to go that route. I think the concern is whether the upgrade will be available right after the cancelation.
