Missing/Hiding history post upgrade

I was wondering if someone could shed some light on my little problem.

I have rt running on machine A with 45k tickets in production use. I
thought I would do a couple of test upgrades on machine B. A is
running Apache1.x, mysql4,redhat7.2, rt 3.0.7 . B is Apache2+mod_perl,
mysql5,CentOS4.4, RT3.6.4 perl5.8.8.

I followed the upgrade instructions and ran the schema/acl/insert
updates for each version, deleted Mason/obj (if there was data).

I still get the following messages when I click on a ticket. I also
get the second error message if I click on ‘basic’. Apart from this,
everything seems to work, I even get the history if I click on
history.

Thanks very muchly for any light shedders out there…

Solved ish.

upgraded in two stages 3.4.6 first which worked fine, then 3.6.4 which
then also worked fine.

Woohoo!
