Direct upgarde means that from 7.1.5 will go to 8.x version with ONLY one upgrade

Non direct upgarde means multible upgardes before you go to desire version

The below shows you from the version that you are now to which version you can go directly(with only one upgrade)

General:

First you have to upgarde the PUB.Then the upgrade version will go to the inactive partision

Then upgrade the SUB.

Once SUB finish and the upgarde version is also to the inactive partition then go and  switch version first to the PUB

Once PUB comes up , then go ahead and do the same with the SUB

After all check the replication status from the Pub to be sure that teh replication is ok between PUB and SUB
