I have known situations where things simply have stalled or appear to have, and one has had to chance it and just navigate back to the dashboard where things were found to actually have completed, I’m not suggesting that this is the case here or that you chance interrupting the process, but that is a long time to wait.

In all honesty I would never upgrade BP this way, I always perform a manual removal and upload of fresh files via ftp or zip upload.
