I was once in a similar position: company merger and they decided to move support offshore. We got 6 months lead notice and generous severance paid out as long as we stayed to the end. Fast forward a year and they took 85% customer approval to 13%. We got hired back at 1.5x our old pay rate, so not quite the 3x you mentioned. Hoping this works out similar for you in the end.
