EPOS migration without closing for a week

An EPOS migration doesn't require closing. Done properly, the heavy work happens before the switch: menus built, data mapped, staff walked through the differences, integrations tested on the side. The actual changeover then fits in the gap between one service and the next. I once replaced a three site group's ten year old stack in an afternoon, and the afternoon was only possible because of the fortnight of preparation nobody saw.

What actually makes migrations slow?

Nobody owns the decision

The single biggest delay in most till switches is the months of not quite deciding. The technical work is days. The dithering is quarters. If the business case is made, set the date first and let the date force the plan.

The menu build gets underestimated

Your menu, modifiers, prices, happy hours and staff discounts are the real data migration. Exporting them cleanly from the old system, or rebuilding them properly rather than copying old mess into new software, is where the honest hours go. It's also a once-in-years chance to fix the product list everyone's been working around.

The joins get left until last

Payments, bookings, stock and accounting connections should be tested before switch day, on the new system, in parallel. The migrations that go wrong are almost always the ones where the till worked fine but the card settlement or the booking feed didn't, and nobody found out until Friday.

The switch weekend, done right

• Old system runs its final service and closes out normally
• New hardware swaps in overnight or during the dead hours, with the old kit kept boxed and reconnectable for a week as the fallback
• First service on the new till is deliberately your quietest, not your busiest
• Someone who knows both systems is on the floor for the first two busy nights, watching real staff use it under pressure

Who this is for

• Operators who know the till has to go but dread the disruption
• Groups staggering a rollout across sites and wanting the first one done right
• Venues coming to the end of a contract with a switch decision attached

What it costs and what to expect

Expect the preparation to take a couple of weeks of part-time attention and the switch itself to fit between services. Expect the first week to be slightly slower while muscle memory rebuilds, which is why you don't switch the week before your biggest trading weekend. The cost that matters isn't the project, it's choosing the destination well, which is a different article.
