Subject: Properly ALTER Column Data?

I know this is very basic for most on the list but I need some MySQL
help. I am logged into my database and I successfully changed a 'field
type' from INT to VARCHAR. Now I need to modify the actual data I
inserted into those specific fields. I checked the manual and could
not really gather exactly how to format my command. There was just so
many options and information on the page...

My table data is as follows and I would like to 'ALTER' the data in
all three 'Serial' fields:

mysql> select Model, Serial, GFE, EOL from sun;
+----------+--------+------+------------+
| Model    | Serial | GFE  | EOL        |
+----------+--------+------+------------+
| Ultra 24 | 941    | 8402 | 2010-10-16 |
| 7310     | 934    |    9314 | 2012-08-27 |
| J4400    | 926    |    7623 | 2012-08-27 |
+----------+--------+------+------------+
3 rows in set (0.00 sec)

Can someone please help me understand how I am to properly use and
change the data in MySQL?
