My upgrade goes as far as this part:
Migrating existing 1 blog into websites and its children...
Then I get this error:
Error during upgrade: Can't call method "site_path" on an undefined value at lib/MT/Upgrade/v5.pm line 413.
My MovableType is in a CGI-BIN folder, I'm using the same config file as with 4.x and I have a MT-STATIC folder. I have a feeling this is something that can be fixed by editing the config file, but I'm not sure.
Reported on Movable Type 4.3
Go to movabletype.org/feedback.html and file a bug report.
Done. I really wish I could have upgraded, though. I've heard great things about MT5.
QA team tried to reproduce this issue, but they couldn't.

If you still have same issue, can you tell us a step to reproduce ?
I had the same problem.
The issue seems to be because the "themes" folder isn't located inside the /mt directory. The installation guide seems to suggest that the /themes directory should be installed on the same level as /mt-static and /mt, however this is apparently not the case.
After moving the folder to /mt/themes, the installation finally managed to finish for me.
Hope that helps!
