 Replying to [comment:6 flixos90]:
 > Maybe we should move the relevant parts here into an actual function,
 something like `upgrade_network_sites()`. This would allow us to better
 add unit tests for it.

 [attachment:37823.5.diff] looks good. Let's hold off on creating an
 `upgrade_network_sites()` or similar until we explore #11869, #37799, and
 others a bit more. We may end up refactoring this page in other ways.
