Update to this for thread for those reading this in the future.
For the JUpgrade to work, I turned on the mootools extension.
In the previous post, I was incorrect about FTP being disabled on DH. You can go back to FTP if necessary but I would only do it for the installation using SP Upgrade (if you go that route) and then turn it back to use SSH, SCP and SFTP.
JUpgrade did not complete as far as what the broswer message was stating. It apparently hung on transferring the images and web data. I let it run overnight but it still wasn’t giving me the “all is complete” sign. However, the site seems operational and I believe everything is there.
