TFS Azure DevOps On prem upgrade 2018 to 2019 question

Question

I want to upgrade to TFS 2019 (Azure DevOps Server), however, all of the instructions I can find are rather disjointed.  Does anyone have a link to a step-by-step guide or something like that?

Answer 1

First, make sure your system meets the requirement set by  Azure DevOps on-premises. If your setup is one server for the “Application Tier” and another SQL database server for the “Data Tier”. It's the same with the environment if you put them in only one physical machine/server. Since the “Data Tier” was already running with SQL Server 2016 (or above) on TFS 2018, so you only needed to upgrade the “Application Tier”. During the server configuration wizard, you could directly configure the production upgrade.
