update from d8 to d9

[naienko]

I'm slow, I know.
Anyway, the update won't go. It says
Can't use an undefined value as a HASH reference at /dw/cgi-bin/DW/User/DVersion/Migrate8To9.pm line 40.
Compilation failed in require at /dw/bin/upgrading/d8d9-userpicrename.pl line 27.
BEGIN failed--compilation aborted at /dw/bin/upgrading/d8d9-userpicrename.pl line 27.

Plus, the update page no longer allows users to select a userpic for their entry, which I'm thinking is somehow related. nevermind, somehow that fixed itself. I don't know.
