IIUC the 5x->7x upgrade won't immediately fail like a 6x->8x upgrade
would, but neither is it really expected to produce the results you
expect due to differences in the index formats.

Shawn, my impression is that you WILL be able to upgrade a 5.x index to 6.x and
then to 7.x for use with 7.x. So your wiki page is a bit too strict here.
But if you ever want to upgrade to 8.x, that version will require the "first
created" version to be 7.0 or later, so you'll need a full reindex

1. We cannot upgrade directly from 5.x to 7.x instead upgrade to 5.5 then
upgrade to 7 as there is major index format level changes taken place in 5.5
or later version.
Solr 7.x cannot read indexes from 5.5. It can only read indexes that
were *full
