Hi,
I was in the process of upgrading vCenter from 6.7.0.51000 to 7.0.2-18455184. The stage 1 of creating new appliance when without a hitch but the stage two throws following error.
Internal error occurs during Export of VMware vSphere Update Manager.
I did saw another thread on the same issue but did not saw any resolution there. Since it was old thread and version was different thought of posting as a new question.
I had a similar error from 6.7.5200

There is a restriction on the upgrade path. You have to have the correct image based on the link below.
This is helpful. Thanks for sharing, Mutthu!
