Can you confirm if data is deleted when upgrading from 1.5 to 1.6?
Also if you backup your 1.5 database, how would you restore it to 1.6 database? I think the only option would be to transfer data using DTS package etc?

I haven't used the upgrade script so I can't confirm if any data is deleted. A quick search of the script only shows DROP TABLE statements for temporary tables.
The upgrade script I was referring to that did delete data was the 1.30 to 1.40 upgrade script (line 11402: "DROP TABLE [dbo].[Nop_Product_SpecificationAttribute_Mapping]". It did this because it altered the table and functionality for the product specifications.
You backup the database (and site) so that you can restore back to 1.50 in the event the 1.50 to 1.60 upgrade fails.
