For hotel groups switching PMS
Fix guest identity before you switch PMS
Every group that’s switched PMS has a guest-data horror story: a loyalty tier reset to zero, a returning guest greeted like a stranger, years of preferences that didn’t make the jump. It isn’t unavoidable. It’s a symptom of where guest identity lives.
- Guest history stays intact, no matter what PMS you run.
- Loyalty and direct-rate status keep working through the switch.

What a PMS switch actually puts at risk
Ask any operations director who has lived through a PMS migration what goes wrong. The list rarely surprises.
Guest history fragments or disappears
Stay counts, preferences and notes recorded in the old system rarely map cleanly to the new one.
Loyalty and membership status breaks
Tier calculations, points balances and direct-rate eligibility get rebuilt from whatever data survives the migration, not from the guest's actual history.
Automation stops working
Any upsell, personalisation or messaging workflow built on the old PMS has to be rebuilt against the new one, often from scratch.
The timeline and budget both slip
Data migration, not the switch itself, is usually where PMS projects run over.
Guest data shouldn’t live inside your PMS
Property management systems were built to run daily hotel operations: reservations, housekeeping, billing. Guest identity got bundled in almost by accident, because the PMS happened to be the system open when a guest checked in.
That bundling has a cost nobody prices into a PMS contract. Change vendors, and you’re not just adopting new software, you’re carrying decades of guest relationships across a migration no vendor has a commercial incentive to get right on your behalf.
It’s the same problem Casa Layer solves for OTAs and booking channels, applied one layer deeper. Guest identity should sit above every system that touches it, PMS included, not inside any one of them.
Your guest history becomes hostage to whichever vendor holds your PMS today.
Resolve identity first, switch systems second
Casa Layer is a guest data layer: it resolves guest profiles, across PMS, POS, booking engine, spa and F&B, into one Master Profile that is independent of any one of those systems. It talks to your current PMS over API. It will talk to your next one the same way.
Weeks 1 to 3 · Resolve
Clean identity against the system you know
Guest identity gets resolved and validated while you still understand the system that data currently lives in, not blind against an unfamiliar new platform. Three weeks from kickoff, before the migration project starts.
Week 4 onwards · Switch
Migrate towards a record that already exists
The new PMS becomes one more feed into a stable, validated record, not the new permanent home for a decade of guest history. Your migration keeps its own timetable; the guest record is already safe.
What survives the switch
The Master Profile sits above your systems rather than inside one of them, so it carries on regardless of what happens underneath it.
Guest history carries over intact
Stay patterns, preferences and notes were never inside the old PMS, so there's nothing to lose in the migration.
Loyalty and direct-rate membership keep running
Tier status and rate eligibility are worked out from the Master Profile, not from the PMS, so they don't reset when the PMS does.
Upsell and personalisation automation don't stop
Any agent or automation you run reads the same stable identity, switch or no switch.
You negotiate the new PMS contract from strength
When guest data isn't the thing forcing your hand, you can walk away from vendor terms you don't like. That leverage disappears the moment your guest history is trapped in someone else's database.
Every switch starts the same way: a guest walks up to a front desk that has never seen them before, even though your group has.
Switching PMS: the questions we hear first
Will I lose guest history when I switch PMS?
Not once it lives in the Master Profile. The Master Profile sits above your systems rather than inside one of them, so stay patterns, preferences and notes were never trapped in the old PMS, and there is nothing to lose in the migration.
Do loyalty tiers and direct-rate status survive a PMS migration?
Yes. Tier status and rate eligibility are worked out from the Master Profile, not from the PMS, so they don’t reset when the PMS does.
Should I resolve guest identity before or after switching PMS?
Before. Resolve identity first, then switch systems. Reverse that order and you inherit whatever the migration got wrong: duplicate profiles, orphaned records, and gaps in history far harder to reconstruct after the fact than to protect beforehand.
How long does it take to resolve guest identity before a switch?
Guest identity is resolved and validated in the first three weeks, before the migration project starts. The new PMS then becomes one more feed into a record that already exists, rather than its new permanent home.
Does Casa Layer replace my PMS?
No. Casa Layer is a guest data layer, not a PMS. It talks to your current PMS over API and will talk to your next one the same way, so your migration keeps its own timetable while the guest record stays stable underneath it.
A PMS switch should be a decision about software, not a referendum on whether your guests get recognised.
Resolve identity first, then switch systems. Reverse that order and you inherit whatever the migration got wrong: duplicate profiles, orphaned records, and gaps in history far harder to reconstruct after the fact than to protect beforehand.
