Need to Upgrade from SQL Server 2012 to SQL Server 2016

Hi All,

I have to plan and upgrade Database from SQL Server 2012 to SQL Server 2016. It is going to be in-place upgrade. I will be doing this in UAT Environment 1st to find out all the challenges in preparation for production upgrade. 

Current Version: Microsoft SQL Server 2012 (SP1) - 11.0.3128.0 (X64)   Dec 28 2012 20:23:12   Copyright (c) Microsoft Corporation  Standard Edition (64-bit) on Windows NT 6.2 <X64> (Build 9200: ) (Hypervisor) 

Upgrading to: Microsoft SQL Server 2016 (SP1-GDR) (KB4019089) - 13.0.4206.0 (X64)   Jul  6 2017 07:55:03   Copyright (c) Microsoft Corporation  Enterprise Edition: Core-based Licensing (64-bit) on Windows Server 2012 Datacenter 6.2 <X64> (Build 9200: ) (Hypervisor) 

I guess many people have done this and would like to hear their experience, challenges and gotcha if any..?

Currently I am following this:
