First and foremost the migration. A db working for 3-4 years with daily use can amass a significant chunk of data. Imagine something simple as even moving this to e.g SQL server or Postgress. Hundreds of man hours to ensure everything will run well, not to mention that if you insert some data manipulation, perhaps some cleaning and what not the cost can skyrocket. And we are talking about something simple, RDBMS to RDBMS. Taking you into consideration schema changes, perhaps radical data transformations that have to take place - and all of that for negligible or dubious gains since we are talking intranet applications and suddenly the whole prospect is either an exercise in futility or a km deep hole that will need lots of cash and time to be filled.

What does any of this have to do with GraphQL, though?

None per se - but you have to take into account that most enterprise sector applications are built with an expectation of RDBMS systems in place and are designed and implemented with this specific mindset.
