# Bring your data across

> Step 2. Get your catalog, stock and customers into TWICE 2.0 one of three ways: build without them, move them through the API, or have TWICE move them.

Pick one of the three ways below and follow it. Configure your settings first ([step 1](https://www.twicecommerce.com/docs/guides/migration/configure-settings.md)): prices and stock attach to your locations, currency and tax setting, so those must exist before any data does. [What changes from TWICE 1.0](https://www.twicecommerce.com/docs/guides/migration/what-changes-from-1-0.md) explains how your data is reshaped on the way.

| | Build without your data | Move it through the API | Have TWICE move it |
| - | - | - | - |
| Who does the work | You, in the admin | Your developer or integration partner | TWICE |
| What moves | Nothing. You create or import from CSV | Locations, SKUs, stock items, listings, prices, add-ons and collections, plus customers if you decide to | Inventory, catalog and customers |
| Suits | A small catalog, or one you want to redesign | A large catalog, and a developer to hand | Handing the work over |
| What it costs | Your time | Your developer's time | Part of an onboarding package |

Orders, deposits and order history stay in 1.0 whichever you pick. [What stays in 1.0](https://www.twicecommerce.com/docs/guides/migration/what-changes-from-1-0.md#what-stays-in-10) lists them.

## Build without your data

Create your stock and catalog in 2.0 with the walkthroughs below, using your 1.0 admin as the reference. Export your stock and customer lists from 1.0 to import them rather than retype them.

## Move it through the API

Hand your developer [How to migrate your data through the API](https://www.twicecommerce.com/docs/guides/migration/migrate-through-the-api.md). They read from the 1.0 API and write to the 2.0 [Admin API](https://www.twicecommerce.com/docs/concepts/integrations/overview.md). Settle the four decisions on that page with them before they write any code.

## Have TWICE move it

Book the Guided or Premium onboarding package. Both include migrating your inventory, catalog and customers, and TWICE configures your account with you. See [twicecommerce.com/pricing](https://twicecommerce.com/pricing) for what each package includes.

Agree in writing with your TWICE contact what moves and by which date, then continue at step 3 when TWICE hands the account over.
