Hi All: I am still in the process of upgrading a few servers from OES 2015 SP1 to OES 2018 (I have not yet tested OES 2018 SP1). I have created dvds from the iso file and the dvd boots fine. However, I keep seeing an error stating the metadata cannot be found on the dvd. I had copied the iso from a server over to my desktop for burning and I am wondering if this has caused a corruption of some sort. I have successfully upgraded other servers with identical hardware without difficulty. The only other difference is that these server are in branch offices.

Any ideas what may be the problem? Thanks much, Chris.
