Sql Server to Teradata migration

We are migrating from sql server to teradata. It is about 500 tables, 5.4 TB data. Plan is to take backup of sql server data in order to avoid any impact on current processing. So, once we take backup on sql server how can this data imported in Teradata?

Can tables/data be imported from .bak file? If not what are the suggestions?
