We currently have a web farm of three servers and the application code is held on a fileshare on a separate device. We are running a project to migrate the applications to a separate storage device which will ultimately have a different root UNC file path.
We previously managed a similar operation on IIS 6 by simply modifying the metabase.xml file, however I don't believe this is a possibility in IIS 8.5
What is the best way to manage this migration considering that the web farm is running 200+ applications? Is there a convenient migration tool or configuration file?
