Hello, I put up my Pro site on WPengine some time ago, and then got distracted and let it fall into disuse.
Some time ago I started getting emails from WPengine that automated core upgrades are failing. I presume this has to do with some Pro feature that was failing automated testing.
I’d like to bring my site up to current version-levels before I get back to updating my content.
I’m currently on WP 4.81 and Pro 1.1.1 (I know).
Is there a guide to this? Can I go to the current version of Pro on WP 4.8.1 and then upgrade the Core?
Thanks in advance for your gentle advice 
Thought I’d better ask the community before I bother Support.
EDIT: I did a little digging and saw no hazards so I ran a backup, updated Pro, and then updated WP. It worked. So, hope that helps anyone who finds this searching.
