Hey @dmacintosh_splu I appreciate that link. I already have that document and use it as part of all of our upgrades. I was more looking for tips/tricks/gotcha's from others who have made the jump from 7.x to 8.x to help prepare for any issues/concerns before we upgrade.
That is great to hear and apologize for misunderstanding the question you were asking. I have personally not heard of much pain from v7.3.x to v8.x, mostly from v7.2.x and prior to anything beyond v7.3.x. I look forward to seeing some other responses, have a great day!
