Maybe? I feel like there's been lots of efforts to migrate large C++ codebases over the years, and few actually complete the migration. Heck, Google is even making Carbon to try to solve this.
migrating any large project is going to be billions of dollars worth of labor. Language isn't a large factor in that cost, you can save few tens of millions at most with a better language.
