To be able to migrate from Oberlo to Topdser, you will need to install the Topdser Chrome Extension.
How to Migrate
You need to go to your Oberlo. Access "My product" page and you can then click Topdser Migration button.
Note: the "Sync to Topdser" button will appear only on the English interface of Oberlo.
You will be notified in the top right corner when it is completed.
When you go back on Topdser, all the products sync to Topdse and the variants will be mapped now.
Why did my migration fail?
The migration will fail in the situations below:
1. Products were not imported from AliExpress but from an Oberlo supplier, you need to find an AliExpress supplier and will need to manually map the products.
2. You are logged in different Shopify stores in Oberlo and Topdser. Check which account is linked to which and where you are logged in.
3. The product is mark as Unavailable on Shopify.
Product is migrated to Topdser, why the varaints still need mapping？
Some merchants may ask why still need to map the varaints one by one after it migrated to Topdser. Normally it's because the variant's name had been edited and changed. You will need to select the variants again, corresponding to the AliExpress product's variants.
