Importing database from legacy aplication

Hi.

I’m rebuilding from scratch a legacy application from php/mysql to
rails/mysql.

At some point I’m going to have to import the data from the legacy
application. One of the reasons for rebuilding is the badly implemented
database.
Also I will have to map the old column names with the new ones and
convert the encoding from ISO-8859-1 to UTF-8.

Should I use migrations or a standalone script for that?
Where should I implement the tests?

Thanks in advance

Sorry
