[1] do your schema upgrade separately [2] disable CRL checking on every server [3] apply the update
I have seen it take as much as an hour and a half, but never 3 hours. I would ask what the 6 hours includes? A full backup of each node? Contingency in case of update failure? I warn clients up front that we need to plan for contingencies, but quote those as add-ons, not base price. Regards, Michael B.

Greetings, We have a simple Two node DAG running W2K8 R2 SP1 and EXCHANGE 2010 SP1 rollup 4.3 and both are on strong HP G7 physical boxes with dual 6 core processors with 48 GIG RAM, so plenty of horsepower. We plan to upgrade each host to EXCHANGE 2010 SP2 and rollup 4 next week. One vendor I checked with indicates that each host will take up to 3 hours to upgrade so we should plan for a six hour project. That seems a bit high, but not sure. Does anyone have experience as to how long this upgrade will take with each host? Any other issues we should be aware of before we start this project upgrade? Thanks for any input.
