Do I pay taxes on 6 months of Georgia employer Severance pay if I moved out of state and established residency in Tennessee after receiving it?

Received 6 months severance package from employer I worked for in Georgia while residing there. After 1 month, I moved to Tennessee and established residency immediately. I am wondering if months 2-6 of severance pay are taxable to GA?
