I currently have a Windows 2008 R2 box that I want to convert to a hyper-v host. Currently I have the following running on it: File Services, Web Server (IIS), and Sql Server 2008 R2 with a few different DBs. In the long term, I'd like to move all of those over to the VMs that will be created. However, in the short term I'd like to leave them running on the server.
Are there any complications/problems with leaving them running on the hyper-v server for a day or two? How long will those services typically go down during the addition of the hyper-v role?
Right now my plan is to back up everything, enable the hyper-v role, set up VMs, and migrate stuff off of the host. However, if there is a good probability that something may cease to function I might need to migrate everything over to a temporary host before doing the conversion.
