Our environment is currently Exchange 2010 SP1, update rollup 6. I want to deploy SP2. I know I have to do another schema update. So all I do is run setup /prepareschema in our Forest root, then wait a few days before rolling out? I also ready that SP1 and SP2 coexist nicely so you can somewhat take your time rolling out but to do it as soon as possible. I plan on getting it done in 1 weekend. I have 15 servers to update. Anyone else upgrade from a similar environment have anything worthwhile to report? Just want to make sure I cover all my bases. As much as you read, test and prepare, it always feels like you are fogetting something. Our Window OS version is 2008 R2.
