We do not recommend repurposing your SKUs into new products or unlinking historical variant listings from your items. These kinds of changes risk the critically important links between the items, listings, and historical orders and can lead to fundamental problems for your catalog.
Potential impacts:
Overselling / underselling due to reserves being held for the wrong listing.
Inaccurate or missed inventory deductions
Inaccurate historical insights and reporting
Simply put, changing how a listing looks does not make also it a fundamentally "new" listing. The original listing will still remain linked to the original item, and reporting would thus become commingled.
Inaccurate velocity based purchasing reports
Shipping rules and tags
How should I handle old products?
As a best practice piece of advice, we don't recommend deleting products or items. A safer alternative to consider that preserves history is by archiving or deactivating products and simply creating a new listing for the new product.
After that:
Go to SKULabs settings > your store > catalog setup settings
Set your listing import settings to Link listings to existing items only
Search for the new listing and ensure it is linked into the correct item/kit
Note: Do NOT delete or unlink old listings from within SKULabs. They are needed for processing and historical orders.
