Variants changing to using

Hi, We are running items with a seperate card for each size/colour. We are looking to switch to variants, but are worried about loosing our historical sales data. Has any one ever started using variants, and what problems were discovered, and what was the quickest way to make the chnage. We are using v3.7 soon to move up to v4 on sql data base, 4000 items, 150,000 item trans actions

You could write a process to convert your existing transaction history (Old item := New Item/variant). This will require a developer’s license to update data in protected tables. Using variants will require some minor form & report changes, as most of them do not display “Variant Code”. Also variants are not supported throughout the system. Intercompany is on place I can think of.
