The PMS Migration Playbook: What Most Operators Get Wrong
I've been involved in more PMS decisions than I can count: evaluating them, implementing them, migrating between them and living with the consequences of both good and bad choices. The mistakes I see operators make are rarely random. They're predictable, they're avoidable and they almost always happen before a single vendor conversation takes place.
This isn't about which PMS to choose. It's about how to think about the decision and how to approach a migration in a way that gives you the best possible chance of getting it right.
Before you look at vendors: the most important decision you’ll make.
Before you evaluate a single platform, you need to answer a more fundamental question: what kind of technology stack do you actually want to operate?
There are two broad approaches and they lead you to very different places.
The first is a best-in-market stack. You select the strongest platform for each function, from property management, revenue management, channel management, housekeeping operations, accounting to key management, and so on. You connect them through APIs and integrations. Done well, this gives you genuine capability at every layer of your operation. Done poorly, it gives you a fragmented, brittle technology environment that your team works around rather than with.
The second is an all-in-one solution. You trade some individual capability for seamless data flow and operational simplicity. You might not have the best revenue management module or the most sophisticated reporting but your data moves cleanly across your business without the complexity and cost of managing multiple integrations.
Neither approach is inherently right. The right answer depends on your business model, your scale, your team's technical capability and your growth trajectory. But this decision has the most foundational consequence on your vendor selection. Because if you're going best-in-market, you're not just looking for a PMS. You're specifically looking for an API-first PMS, built to connect cleanly with the other platforms in your stack. Selecting a closed or integration-limited system in that context isn't just a limitation. It's a strategic mistake that compounds over time.

Go on your own journey.
One of the most common mistakes I see operators make is letting the market make their decision for them. They look at what a competitor is using, or what the large operators in their segment have implemented, or what gets mentioned most often at industry conferences. They then treat that as evidence of what they should do.
It isn't.
Every business is unique. You have built your own processes, your own ways of working, your own stakeholder relationships. The reasons another operator chooses their PMS may be completely specific to their ownership structure, their distribution mix, their legacy integrations or decisions made five years ago under very different circumstances. You are not them.
Go on your own journey. Start with your own requirements, your own strategy, your own definition of what success looks like. Then evaluate the market against that. You'll make a better decision and you'll be far better positioned to get value from whatever you choose.
Write everything down. Every requirement.
Making assumptions is entirely human. It's also one of the most reliable ways to end up in a migration that doesn't deliver what you needed.
The requirements document is the single most important output of your entire evaluation process. Not the vendor demos. Not the feature comparisons. The requirements document forces you to be specific about what you actually need, before you're sitting in a sales environment being shown what a vendor wants you to want.
Write down every requirement. Not a summary. Every one.
And when you write them down, work with the vendors. They've seen your requirements before, almost certainly. They know the workarounds, the configurations, the approaches that accommodate complex needs. A vendor conversation grounded in specific requirements is completely different to a generic demo. The answers you get will tell you far more about whether the platform is actually right for you.
Don't hope for the best. Don't assume it'll work itself out. Don't defer the hard questions to the migration itself. By then, you're working under time pressure, against a go-live date and the options available to you have narrowed considerably.
Put yourself in every stakeholder’s shoes.
This is where I most often see even experienced operators fall short: they write requirements from the perspective of their core operational team and miss everyone else.
Your PMS doesn't just serve your reservations and front desk teams. It serves your finance team processing invoices and managing complex GST or VAT calculations. It serves your owners who need real-time visibility into their property's performance. It serves the outsourced housekeeping team that needs access to booking data to manage their workflow. It serves the corporate accounts manager who needs to pull specific reporting. It serves the asset manager who wants to see performance against benchmarks at a moment's notice.
Every one of those stakeholders has requirements. Owner reporting, which is real-time, accurate, and accessible, is the area where I most consistently see operators underestimate complexity. It looks simple until the first month-end when an owner calls because their report doesn't reconcile, or because the platform doesn't support their reporting format or because access requires a workaround nobody documented.
Before you finalise your requirements document, sit with every team and every stakeholder group and ask them specifically: what do you need this system to do? What would make your job harder if it weren't there? What does the current system do that you depend on, even if you've never thought of it as a feature?
You'll find things you hadn't considered. That's the point.
Create a clear migration plan and respect the complexity of data.
Selecting the right platform is half the work. Migrating to it is the other half. It's consistently underestimated.
The core challenge is that you cannot close your business for a migration. You will be taking reservations, managing existing stays, processing payments and running your operation on the day you switch systems. That's not a background consideration. It's the central constraint around which your entire migration plan needs to be designed.
Data transfer is hard. Your historical reservation data, rate structures, guest profiles, corporate account configurations and financial records need to move to a new system cleanly, accurately and verifiably. The data you have is almost certainly messier than you think with duplicates, legacy formats and fields that don't map cleanly to the new platform's data model. A thorough data audit before migration is not optional. It's the difference between a migration that goes smoothly and one that surfaces problems you don't have time to fix.
A clear migration plan covers:
What data is being migrated, what's not and why.
How data quality will be validated before and after.
What the parallel running period looks like. Trust me, it should be longer than the vendor recommends.
What the rollback position is if something goes wrong.
What training timelines look like, with enough lead time for the team to build genuine capability before go-live, not just familiarity in the final week.
Go-live dates have a way of becoming politically fixed before the migration is actually ready. A delayed go-live is recoverable. A failed go-live is expensive, disruptive and occasionally damaging to guest experience in ways that take months to repair.
What good looks like.
A successful PMS migration leaves your team operating confidently on a new platform, with clean data, working integrations and the capability to use the system effectively without ongoing external support. Within sixty days of go-live, it should feel like the new system is simply how you operate, not like a project that's still in progress.
That outcome is achievable. It requires doing the thinking upfront that most operators skip: getting clear on your technology philosophy, defining your own requirements, documenting every stakeholder's needs and planning the migration with the rigour it deserves.
If you're working through a PMS decision and want to talk through your situation, I'm happy to have that conversation.
