Run both systems until 1.0 is finished

Step 9 of migrating from TWICE 1.0. 1.0 keeps every order made before the switch and runs them to completion. 2.0 holds everything from the switch onward. This is the longest step and the one most often under-planned. How long it runs is decided by your longest-dated booking, not by you — if you take bookings a season ahead, 1.0 stays open a season. If everything you sell is fulfilled at the point of sale, this step is days.

​

Working 1.0

Fulfil collections, returns, extensions, cancellations and refunds for pre-switch orders in 1.0. Release deposits in 1.0, from the 1.0 order. Bookings dated after the switch are still 1.0’s. A customer who booked in 1.0 for a date next month is fulfilled in 1.0 on that date, even though 2.0 has been live for weeks by then.

​

Watching 2.0

For the agreed period after the switch, check daily:

• Every order received its confirmation email.
• The day’s collections and returns match what actually happened at the counter.
• Payouts arrive, and the amounts are correct.
• Whether anyone is working around the system. This is the most useful signal you have — a workaround is a defect report from someone too busy to file one.

Hold the scheduled check-in with TWICE for the agreed period. Bring the workarounds.

​

Closing 1.0

Keep 1.0 readable until all of these are true:

• Every pre-switch order is closed.
• Every deposit taken in 1.0 is released or charged.
• Every refund owed on a 1.0 payment is handled.
• Finance exports and retained records are stored outside TWICE.
• Your accountant has confirmed they have what they need.
