I was hired at a small startup (~15 employees total) and one of the first things I did was to migrate their SVN repository to Git. Not too difficult, brought over the history and then had to write a bunch of tooling to handle the fact that not all of the source code was in one giant heirarchy anymore (since everything was microservices and self-contained libraries it made sense to split them out).

After I left that company I ended up at a larger company (~14k employees) in part because I'd worked on SVN-to-Git migrations before. Definitely a different beast, since there were a huge amount of workflows that needed changing, importing 10 years of SVN history (some of which used to be CVS history), pruning out VM images and ISOs that had been inadvertently added, rewriting tons of code in their Jenkins instance, etc.

All this on top of installing, configuring, and managing a geographically distributed internal Gitlab instance with multiple repositories in the tens or hundreds of gigabytes.

It was a heck of a ride and took years, but it was a lot of fun at the same time. Thankfully 'the guy who suggested the transition' was the CEO (in the first company) or CTO (in the second) nothing went wrong, no one got thrown under buses, and both companies are still doing a-okay (as far as source control goes).
