Using c# to move data from one sql server to another.

Question

We just redesigned, and rewrote, our application with brand new designed database schema.

My next job is to write c# code that will convert and move the data from the old database to the new database.

.

I'm a simple man. I just want to read the data, massage the data to convert it to the new tables' format, and insert the data into the new database.

. 

The system architech wants to use reflection, POCO, Json and maybe even a dictionary to do this. I'm asking myself why make this so complicated?

I don't even know if I know how to do what he wants.

Can someone give me a hint of what the architech is talking about? 

 

Thank you.
