Host migration

I have just moved a customer to a different host.

When I imported the DB a large number of the products changed there manufacturer from none to a particular manufacturer.

Is there a way to globaly change the manufacture for all products to none rather than the wrong manufacturer?

I also noted that a number of the products changed images (not all products have images).

Why not just reimport the product table?

And I'm rather curious as to how you moved the data in the first place causing the changes ...

On the original host I used phpmyadmin to export the entire db.
When I found the manufacturers problem I exported the products table from the original site. Then on the new site I used phpmyadmin and deleted the products table and imported the products table I had exported earlier from the original site, still the same problem.

It has me a bit perplexed, so I suspect I have overlooked something during the export/import process, but not having any real knowledge I have no clues as to what to look for.
