Upgrading from 3.3.7 to 4.0.9 Error

[RagnaXBL]

After attempting an upgrade apache brings up an internal server error while tring to access the login screen

this is what i've seen in the apache error log

[Wed Jul 15 10:57:49 2015] [error] lookup of 'Apache2::Reload::handler' failed
[Wed Jul 15 10:57:49 2015] [error] [client 180.76.15.19] Can't locate /opt/otrs/Kernel/Config/Files/ZZZAAuto.pm in @INC (@INC contains: /usr/Custom /usr/Kernel/cpan-lib /usr /opt/otrs/Custom /opt/otrs/Kernel/cpan-lib /opt/otrs/ /etc/perl /usr/local/lib/perl/5.14.2 /usr/local/share/perl/5.14.2 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.14 /usr/share/perl/5.14 /usr/local/lib/site_perl . /etc/apache2) at /opt/otrs/Kernel/cpan-lib/Apache2/Reload.pm line 179.\n

any idea what the issue could be?

It means what it says on the box.

i restored all the the files mentioned in steps 4.1, went through it again just to make sure i didn't miss anything.

still no dice

The error log is complaining that it can't find a file and you've verified that the file exists in the location that the system can't find, and its case and spelling match?

I don't believe it.
