Well, good news... I spent several hours last night upgrading (I know that is a long time, but I have to be really careful the first time!). And my board came up with no problems after the upgrade. This really boosts my confidence in installing Threads.

One issue: In the control panel, I occasionally see some errors, like this one:
Quote
Can't locate warnings.pm in @INC (@INC contains: ./Modules . /usr/libdata/perl/5.00503/mach /usr/libdata/perl/5.00503 /usr/local/lib/perl5/site_perl/5.005/i386-freebsd /usr/local/lib/perl5/site_perl/5.005 .) at /usr/local/psa/home/vhosts/whitneyportalstore.com/cgi-bin/ubb/cp2_content.cgi line 3843.
when I select the Styles option. I get the same message when I select any of the Content Management group.

I couldn't find any warnings.pm file in the installation zip.
