I actually just upgraded from v11e to v12 this last Friday and had to do a deployment removal of all the old clients and pushed out new deployment of the latest MSI to all our computers on the domain. While our eCW is cloud based, in the next 3 weeks we will be installing a local/on premise test server for our EHR specialist to train providers and other clinical staff along with new hires.
I am though interested in what reports and deployments you have to share!
