Introducing products offline and migration

[cellnet]

Hello Good Morning.
I installed Virtuemart 2.0 on Joomla 1.7 and would like to introduce over 1000 new products. The idea is to do everything offline and migrate in groups. I wonder if since the migration option can do this. I have already entered the categories, manufacturers and some products.
Thank you.

P.D.
I can't use CSV Improved. Joomla 1.7 don't support

why not just dump a copy of the products from the DB into your new DB.. or rename the tables in your DB if they are already there.
