Rollback option in case of In-place upgrade of Windows server 2008 R2 to 2012 R2 Fails
There is no roll back, if the upgrade fails to start then no changes will be made. If something goes south somewhere in the middle then you could be left with nothing. The much cleaner / safer (100%) method is to clean install, patch fully, migrate roles / applications over to it. Something here might help.
