How to change every nvarchar column to varchar?

Question

what would be the simplest way to change every nvarchar column in a database to a varchar?

I personally would prefer nvarchar, but the data arch has specified that v

Answer 1

Ask the data arch to do it?

or

Generate a script of all objects in your system, alter then nvarchar's, then create a new database and import the data into it from the old one.

or

Write alter scripts to update the existing database.
(This may be the best approach if it's a production database, or a client database.)
