Fear of losing bookings often makes managers stick with software they no longer like. A well-prepared migration is still very manageable.
The short answer
Never switch PMS at random between two bookings. Take inventory, export your data, connect channels one by one in a set order, then check every future booking before shutting down the old system.
Step 1: take inventory
List properties, platforms, future bookings, rates, rules (minimum stay, arrival days), automatic messages, open security deposits, team access, providers, owners and documents.
Step 2: choose a window
Avoid a busy period. Let the team know and keep the old PMS readable during the transition.
Step 3: reconnect the channels
First disconnect the listing from the old tool, then connect it to the new one: two programs connected to the same listing contradict each other. After each connection, compare bookings and availability over a long period, at least up to your last known booking. Delete old iCal links that pointed to the old tool.
Step 4: test the automations
Send a test message, create a dummy direct booking if possible, check that the cleaning job is created and check the prices being published. A migration is done when the automations work, not when the properties are created.
With Boostinghost
Create your properties, fill in the welcome books, then connect Airbnb, Booking.com, Vrbo and Expedia by API, and the other platforms by iCal. Once each connection is in place, check one by one that every future booking shows up in the calendar. Then recreate your scheduled messages, cleaning team and security deposit rules. The 14-day trial, with no credit card, lets you switch a first property before rolling out. For the detailed list, follow our checklist for onboarding a new property.
Frequently asked questions
How long should you plan?
From a few hours for one or two properties to several days for a large portfolio with many automations. Move property by property rather than all at once.
Should I delete the old PMS right away?
No. Keep temporary access, disconnected from the platforms, to find a past record or piece of information for a few weeks.
Can messages be migrated?
It depends on the platforms and available exports. Conversations stay available on the platforms; message templates, however, have to be recreated in the new tool.
What about security deposits already requested?
Finish their cycle in the old tool or with the original payment provider, and only turn on security deposits in the new PMS for new bookings.
Key takeaways
Inventory, a quiet window, channel-by-channel connection and a check of every future booking: that's the method that avoids nasty surprises. Never keep two tools connected to the same listing.
