vCenter 6.5 to 6.7 upgrade

Hi

im considering upgrade my vcenter server from 6.5u3g(15505374) to vcenter 6.7u3f(15976714).

i read the "back in time release upgrade restrictions (kb67077)" i looked over the matrix and noticed that my vcenter is not upgadable.

i check the release dates of the version and i can see that my vcenter has no "back in time" secnario. (and yet, it appears as no upgradeble at the matrix.)

my vcenter version and release date: vcenter 6.5U3g 15505374 released 1/30/2020.
the latest vcenter version and release date:vcenter 6.7 15976714 released 4/9/2020.

do i miss something?

i have to make sure before any progress on my evvironment.

thanks for your help
