Migration question from a Newbie

[dev2013]

Hi everyone,
I am about to start a shopping cart with Virtuemart. the client already has the MYSQL database of Categories, Sub categories, and products, which has a lot of data in it, and need to be transferred to Virtuemart database.
what's the best way?
is there any ready product to do that?
shall I program it, and fetch and insert record by record? is it do-able?

I would appreciate any advice.

does he have a proprietary cart, or is it a commercial or open source cart

there are services that can do the migration
look for cart2cart

thanks for all advices. the existing shopping cart is customized one  in Cold Fusion  with MYSQL database. all I would need is to transfer the items records to the Virtuemart database.  it will be new shopping cart system using Virtuemart.
I contacted cart2cart. and sent them the files. waiting for their response.

thanks for all your helps.
