Confused
"The types of apps that will pose the biggest problems are custom-built, in-house apps, especially where the authors have moved on, and apps that have been heavily customized. Typically these are data-intensive and mission-critical, like ERP."
"Three quarters of those that do have a migration plan have the cloud in their sights."
I'm struggling to reconcile these two statements. If you are still on 2k3 because of app-compat, how the hell is the cloud going to help? Either you can find a supported OS for those apps or you can't. Running on virtualised hardware isn't going to help.
