Gilbert Quevauvilliers takes us through version control with PBIX files:
In the second part of my blog post I am going to detail how to use the version control with Power BI Desktop files.
This will include adding files, checking files in and out, viewing previous versions and reverting to previous versions.
If this is the first time you are reading this blog post, I would highly suggest reading Setting up Version Control for my Power BI Desktop Files (PBIX) with no additional Cost * | Part 1
In short, Gilbert treats PBIX file as any other data file. These can get kind of beefy, though, so I’ve also saved them as templates—that way, you get the structure without pulling in all of the data.
