Taryn Pratt had a post-upgrade problem:
Recently, I kicked off a project to start moving us to SQL Server 2019. During my initial review of our servers, I found quite a few (9 total) that were still running on Windows Server 2012 R2. This meant that I would need to upgrade the operating system and move us to SQL Server 2019. Having completed plenty of SQL Server upgrades, as well as operating system upgrades, I couldn’t possibly make a mistake, right? Wrong…I completely forgot to script out the linked servers on the server I upgraded this week. I screwed up and decided to write about how I went about fixing it.
