Hotel PMS Data Export: What You Need Before Leaving Your Old System

What Usually Gets Left Behind

Switching PMS systems gets framed as a technical transfer problem. The real risk is different: it is a record-keeping problem. Operators who have been through a migration often describe the same experience — they exported data, but not all of it, and not in a format the new system could read.

The hotel PMS data export conversation usually happens late in the vendor selection process, after the contract is already signed. By that point, the migration timeline is fixed, the old system is being wound down, and there is limited time to discover what was missed. This article covers the six record categories you need to get out before your access ends.

1. Active and Upcoming Reservations

This is the most obvious export and the one most operators get right — partially. The partial failure comes from specific reservation types.

Confirmed upcoming reservations are usually exported correctly. What gets missed: group reservations that span multiple rooms or carry custom rate agreements, reservations with linked extras such as late checkout fees or breakfast add-ons, and bookings where the original OTA source channel adjusted the rate after the initial confirmation.

Export the full reservation record, not just the summary view. You need arrival date, departure date, room type, rate per night, total amount, source channel, booking date, modification history, and any free-text notes added by staff. A reservation export that omits the source channel field makes it impossible to reconcile migration-period revenue by OTA — you will have revenue figures with no channel attribution.

Also export cancelled reservations from the last 90 days. Cancellations during the migration window may generate refund requests after you have already moved systems, and you will need the original record to process them.

2. Guest Profiles

A guest database is the most undervalued export in a PMS migration. Most operators export it late or skip it entirely, because it does not feel as urgent as reservations.

The practical value becomes obvious at the front desk. When a guest who has stayed six times walks in, your staff should see that history — their preferred room floor, their dietary note from the last stay, whether they have ever disputed a charge. Without the profile export, that context resets to zero on migration day.

Export contact details, stay count, stay history, communication preferences, and any notes attached to the profile. The stay history is particularly important because some PMS systems can import it directly, allowing your team to see prior stays from day one rather than watching the database rebuild itself over the next twelve months.

Format varies by system. Some export guest profiles in CSV with one row per guest. Others use JSON with nested stay records. Confirm what format your new PMS can accept before you start the export, not on the day of.

3. Payment Records and Outstanding Deposits

Payment records serve two purposes after a migration. First, they are your evidence in any dispute that surfaces after the switch. Second, they are needed for any guest with an outstanding deposit or partial payment — those balances need to travel with the reservation record.

Export payment records with transaction IDs, dates, amounts, payment method, and the reservation they are attached to. Export deposit records separately and match them against the upcoming reservation list. Any reservation in your upcoming export that carries a deposit also needs a corresponding payment record attached to it.

Outstanding balances — guests with charges that had not been settled at the time of migration — need separate handling. Build a list of unsettled balances before migration day. These cannot be transferred automatically, but you need the list to know who to follow up with once you are in the new system.

A scenario that comes up regularly: eight months after migration, a guest disputes a charge from a stay that crossed the migration date. Without the original payment record and the matching invoice, you are working from a partial picture, and the dispute timeline is already running.

4. Invoices and Folios

Invoices are not the same as payment records. A payment record confirms that money moved. An invoice shows what was charged, to whom, on what date, and under which tax rate.

In most markets, invoices are required records for VAT or tax compliance purposes, typically for three to seven years after the transaction date. Your old PMS holds those records. When you close the account, they go with it unless you export them first.

Export invoices as PDFs for archival storage and as CSV or structured data if your new PMS can import invoice history. At minimum, export and store locally: invoice number, date, guest name, line items, tax amount, total, and payment reference.

Group invoices — for corporate accounts, event bookings, or travel agent arrangements — require extra attention. These are often managed in a separate section of the PMS and are regularly missed in a standard reservation export. Pull them explicitly.

5. Room Types and Rate Plans

Room type configurations do not transfer. Every PMS stores room type definitions differently — bed configuration, maximum capacity, accessibility features, descriptions, and photo references. You will re-enter this data in your new system regardless.

What you want from the export is accuracy, not migration. Export your current room type list with all parameters so you are re-entering from a confirmed record, not from memory. Errors in room type setup create problems downstream: incorrect OTA listings, availability sync failures, and pricing mismatches. Finding a setup error three weeks after going live is avoidable.

Rate plans are more involved. Export your active rate plans: standard rack rates, direct-booking rates, OTA net rates, corporate account rates, and seasonal variations. Note which channels each rate plan was active on. Your new PMS will need this to configure channel manager sync correctly.

6. Historical Performance Reports

Historical reports are the data category that surprises operators most. They export reservations, payments, and guest records — and then realize they have no occupancy history, no ADR trend, no channel performance data.

This matters because your new PMS starts tracking from day one. Without historical reports, you have no baseline. You cannot tell whether February occupancy this year is better or worse than last year, because last year's data did not come with you.

Export at least two years of monthly occupancy rate, average daily rate, and revenue by channel. Export these as raw data files, not PDF reports. A PDF is readable but cannot be imported or analyzed. A CSV with one row per month and columns for occupancy, ADR, RevPAR, and channel revenue gives your new system a reference point during the first year of operation when trend comparisons matter most.

When your new PMS has a reporting module pulling from live reservation data, the historical CSV is what you use to compare this month against the same month two years ago — the kind of comparison that tells you whether growth is real or seasonal.

FAQ

What data can you export from a hotel PMS?

Most PMS systems support export of reservation records, guest profiles, payment transactions, invoices, room type configurations, and historical performance reports. Export formats vary — CSV is the most common for reservation and guest data, while invoices are typically available as PDFs. Confirm what your current system can export and in what format before committing to a migration date.

How do I export guest data from my hotel PMS?

Navigate to the guest management or CRM section of your PMS and look for an export or download function. Most systems export guest data as CSV with fields for name, contact details, stay count, and last visit date. Some include full stay history; others export it as a separate file. Request the field specification from your vendor and confirm that the new system can accept it before starting.

What hotel PMS data should I back up before a migration?

Back up six categories: confirmed upcoming reservations, guest profiles with stay history, payment and deposit records, invoices and folios, room type and rate plan configurations, and two years of historical performance reports. Store copies in a location independent of both PMS systems — a shared drive or local storage — so the data remains accessible regardless of what happens during the transition.

Can you import historical reservation data into a new hotel PMS?

Some PMS systems support direct import of historical reservation and guest data; others require manual entry or partial import. Format compatibility is the deciding variable — the export file from your old system must match the import schema of the new one. Send your export files to the new vendor before migration day and ask specifically which data can be imported automatically and what will need to be entered by hand.

What happens to hotel PMS data after you cancel your subscription?

Most PMS vendors deactivate account access when the subscription ends and delete stored data within 30 to 90 days. Some offer a data archive request during the notice period, but this is not guaranteed. Do not rely on the vendor to preserve your data — complete all exports before the contract ends. Once access is revoked, recovery is typically not possible.

How long should hotels keep exported PMS data?

Keep reservation records for at least two years for dispute resolution and operational reference. Keep invoice and payment records for the full duration required by your local tax authority — five to seven years in most markets. Guest profile data should be managed according to your privacy policy and any applicable data protection laws, with a defined process for deleting profiles that exceed your stated retention period.
