Q. How different are the concepts of migration, emigration and immigration?

The Migration is the moving of individuals of a species from one place to another. The Emigration is the migration seen as an exit of individuals from one region (to another where they will settle temporarily or permanently). The Immigration is the migration seen as the settling in one region (permanently or temporarily) of individuals coming from another region. Thus individuals emigrate "from" and immigrate "to".
