OMG I was a few FAANG-like companies. Most acquisitions failed due to the migration. It always played in the same way:

1. The acquired company was small company to the acquirer. 2. We need to improve scalability and reduce cost!

Then, they migrated. The new system was worse and didn't have parity. It was years. Customers were moving off. The project/product shut down.
