We are planning an upgrade from SharePoint 2007 to SharePoint 2010. We have a large environment where we have multiple users who could have running workflows at the time of the upgrade (in some cases, our users won't even know if they are running or not). Does anyone know if there is any issue with this that we should be aware of? I am hoping this is a non-issue, but would like to be prepared just in case. Thanks in advance for your help!
