# Check what was migrated

> Verify the migration against 1.0 yourself, and know what deliberately did not move.

Step 1 of [migrating from TWICE 1.0](/docs/guides/migration/overview). Verify the migration yourself before you change anything — once you start editing, you lose your reference point.

## What moved, and what did not

| Item                                | Migrated | What to do                                                                                                          |

| Customer records                    | No       | Customers are re-created when they order in 2.0. You can export the customer list from 1.0 and import the profiles. |
| Future bookings                     | No       | Bookings created in 1.0 stay in 1.0 and are fulfilled there — including any dated for after the switch.             |
| Stock currently out with a customer | No       | It stays in 1.0 and is returned there.                                                                              |
| Completed order history             | No       | Stays in 1.0. Export it before access ends (step 7).                                                                |
| Deposits you are holding            | No       | Released in 1.0, from the 1.0 order.                                                                                |
| Invoices and finance history        | No       | Export from 1.0 before access ends (step 7).                                                                        |
| Payment provider connection         | No       | Connect payments in 2.0 (step 3).                                                                                   |
| Staff logins and roles              | No       | Invite users again in 2.0 (step 6).                                                                                 |
| API keys and integrations           | No       | New keys and a new endpoint (step 7).                                                                               |
| Web addresses                       | No       | 1.0 URLs do not redirect (step 7).                                                                                  |

This is what moves by default. Anything else moves only if it was agreed in your migration scope.

## Reconcile by value, not by row count

Counting rows tells you the migration ran. It does not tell you it was right — a price that moved a decimal place, or an add-on that did not come across, leaves the row count identical and the catalog wrong.

Check totals: total stock value and total catalog value against the same figures in 1.0. Where they differ, find the specific listing rather than accepting the gap.

<Note>
  Reconciling by value is the check most often skipped, and the one that surfaces problems while they are still cheap to fix. A price error found now is a correction; found after go-live it is a refund.
</Note>

## Done when

* Stock item counts in 2.0 match 1.0, per location.
* Listings match on price, or you have confirmed the new pricing is deliberate.
* Rental periods, add-ons and buyback prices are correct.
* Collections contain the listings you expect.
* Total stock and catalog value reconcile against 1.0.
* Anything that did not reconcile is written down, reported, and has an owner.
