Add something like the portal upgrade now has that shows list of upgrade tasks, mark which is currently being performed and the status, and marked completed successfully as it continues to the next. If not that at least a valid progress bar or percent complete so that it is east to see what is left to be processed and if there's an issue that caused it to be locked up or stuck. With a multi server environment and 1 server upgrading 5-10 times faster it would help to be able to see if it's still working and we need to wait, or if it's run in to an issue.
