Moving Fields From One Table To Another

I am currently working on updating a database that I created four years ago for a commission record

there are the tables

table 1:

product ID
Carrier Code
Type
State Available
Updated

table 2:

Product ID
Product name
Sub-name
Street Comp
GA Comp

After refreshing my creation, I realized that Product name and sub-name from table 2 should be going to table 1.. How can I move those two fields from table 2 to table 1 without mess up the data?
