# Clear the external dependencies

> Labels, domains, links, integrations and 1.0 exports — the work that depends on other people.

Step 7 of [migrating from TWICE 1.0](/docs/guides/migration/overview). Everything here depends on suppliers, DNS propagation, or someone else's system. **Start it early** — none of it is difficult, and all of it is slow.

## Labels and barcodes

If stock codes changed during the migration, reprint barcode and QR labels. A default migration should match 1.0 exactly, so check before you reprint anything.

## Domains and links

Set your store address under **Settings → Domains** — the TWICE subdomain, or your own custom domain, and which one is primary for search engines.

<Warning>
  **1.0 links do not redirect.** Old product and order URLs break at the switch. List every link you control and update it before you switch: your own website, business and directory listings, social profiles, email signatures, paid ads, and QR codes on printed material and signage.
</Warning>

Assign each place your old links appear to a named person. This is the item most often discovered after the switch, by a customer.

## Integrations

Anything connected to 1.0 needs a new API key from **Settings → Integrations & API** and repointing to the 2.0 endpoint. Webhooks are configured in the same view.

Test each integration against 2.0 **before** you switch, not on the day.

## Exports from 1.0

Export and store outside TWICE, before access ends:

* Finance and accounting reports
* Your customer list
* Completed order history
* Any documents or signed waivers you are required to retain

Confirm with your accountant what must be kept and for how long. That answer is a legal one, not a TWICE one.

## Done when

* Labels are reprinted, or confirmed unnecessary.
* Your store address is set and any custom domain is verified.
* Every place your old links appear is listed and assigned to someone.
* Every integration has a 2.0 key and has been tested against 2.0.
* 1.0 exports are downloaded and stored outside TWICE.
