Ignition 7.6.7 version to 8.1

Upgrading from 7.8.5

I am looking to plan how long it would take me to upgrade from 7.8.5 to 8.1 I see a guide for 7.9 to 8. Would that be the same as 7.8 to 8 and suffice as a guide? Or might there be additional things I should be concerned about? Also I really didn’t see in the guide, do you just import the 7.8 project into 8.1 and correct the differences in the guide, Or do you need to manually recreate windows? Thank you in advance
