The average CRM migration for a UK estate agency takes 16 days. Not the 2 to 6 months often quoted. Not the business-stopping disruption most agents imagine. Sixteen days – and over 90% go live with zero issues.
So why are so many agencies still running on systems they’ve outgrown? The same outdated software. The same clunky workflows. The same features that haven’t been updated in years. The answer, almost always, is fear of migration.
That fear is understandable. It’s also largely unfounded – and it’s costing agents more than they realise. Here’s what you actually need to know before you switch, the questions to ask any provider before you sign, and the one piece of advice circulating in the industry that could seriously damage your agency if you follow it.

The advice that could cost you years of leads
There is a view that circulates in the industry – sometimes pushed during CRM sales processes, sometimes offered as practical migration advice – that switching systems is a good opportunity to ‘start clean’. Archive the old data. Do not bring it across. Fresh start, fresh system.
It sounds tidy. It is actually one of the most damaging things an estate agency can do.
Your CRM data is not just a list of names and phone numbers. It is the accumulated intelligence of your business. Every applicant who registered and has not bought yet. Every landlord relationship built over a decade. Every vendor you valued three years ago who has not listed yet. Every interaction, preference, and transaction history your team has gathered since you opened.
Some agencies have 15, 20, even 25 years of client and property data in their current CRM. That is not clutter to be cleared on the way out. That is competitive advantage.
And here is why this matters more now than it ever has: AI.
The estate agency CRMs being built for the next decade are AI-native. They use your historical data to identify which contacts are most likely to list, which landlords are most likely to expand their portfolio, which buyers are ready to move again. The richer and longer your dataset, the more powerful those tools become.
AI analysis can build comprehensive client profiles from interaction history, surface which leads are highest priority, predict market-ready sellers before they have even started looking, and identify opportunities your team would never find manually. But only if the data is there.
An agency that starts clean loses all of that context. It starts the AI era with empty hands.
When Alto migrates you, everything comes. Every record. Every note. Every piece of history. No cleansing restrictions. No fields that do not map over. No forced decisions about what to leave behind. If it is in your system, it comes with you.
“We had huge volumes of historical data and understandably, that made people nervous. But Alto’s team handled the migration seamlessly. We didn’t lose anything, and we didn’t lose any time.” – Colin Deer, Managing Director, Chase Buchanan (8-branch agency, 15+ years of legacy data)
The most common questions agents have before a CRM migration
What is CRM migration for estate agents?
CRM migration is the process of moving all of your agency’s data – contacts, properties, transaction history, notes, applicant records – from your current software to a new system. For estate agencies, this includes sales and lettings data, client accounting records, and years of interaction history. A full migration means nothing is left behind. A partial migration – or starting clean – means some or all of that history does not come across.
How long does CRM migration take for an estate agency?
Most estate agent CRM migrations take around 16 days from start to go-live. That is the average across Alto’s 1,600+ completed migrations. Industry guidance sometimes quotes 2 to 6 months, but that typically reflects legacy enterprise systems with heavy customisation, not a well-run estate agency CRM switch.
The process: Alto’s team guides you on what to request from your current provider. Within 48 hours of receiving your files, you get a full test version of your data in the new system. Over 70% of migrations need zero fixes at that stage. Final import and go-live follows, with UK-based onboarding support throughout.
Will we lose any data during the migration?
With a provider that knows what they are doing: no. The risk of data loss in estate agent CRM migration comes from two sources – providers without the experience to handle complex exports, and advisors who encourage agencies to reduce their data before moving. Both are avoidable.
Alto has migrated data from over 50 different CRM systems including Reapit, Street, Jupix and DezRez, and over 90% of migrations go live with zero issues. The questions to ask any provider: what percentage of your migrations require fixes during testing? What fields might not transfer? What are your limitations? If they hesitate, push harder.
Do we have to run two systems at the same time during migration?
No. The ‘dual running’ period – paying for two systems, training staff on both, maintaining parallel workflows – is one of the real hidden costs of a poorly managed estate agent CRM migration. Alto’s process is built around zero downtime. Your team keeps working normally right up to go-live.
What data actually transfers in a CRM migration?
With Alto: everything. Sales and lettings records. Accounting data. Property history. Contact notes. Transaction history. Legacy applicant data. Custom fields. All of it, from any format, with no cleansing restrictions.
This is not universal. Some providers have documented limitations on fields they can map, or only transfer active records – leaving archived and historical data behind. Before signing with any provider, get a written answer to: what exact data will and will not transfer from our current system? If the answer includes any version of ‘you probably will not need that’ – that is a red flag.
What if our data is messy or incomplete?
Messy data is not a reason to delay a CRM migration. It is a reason to make sure you are working with a team that has seen it before. Alto’s migration specialists have handled partial exports, duplicate records, missing field relationships, legacy quirks and bespoke database structures. With 45+ years of combined experience across the team, they know where problems hide before the migration starts – not halfway through it.
The difference between experienced and inexperienced teams: experienced teams anticipate and resolve issues before import. Inexperienced teams discover them during, and improvise.
Should we clean our data before migrating?
There is a difference between sensible data hygiene and abandoning your history. Removing genuine duplicates or correcting obvious errors before migration is reasonable. Using migration as an excuse to strip out years of historical contacts and applicant records because they look old is not.
Old data is not dead data. An applicant who registered five years ago and never bought might be ready now. A landlord who moved to a competitor three years ago might be looking to switch back. A vendor you valued in 2021 might finally be ready to list. In an AI-native CRM, that historical depth is exactly what powers predictive features. Stripping it trades long-term capability for short-term tidiness.
What should we ask a CRM provider before agreeing to migrate?
Eight questions that separate genuinely experienced providers from everyone else:
- How many migrations have you completed specifically from our current CRM?
- What is the experience level of the people doing the actual data mapping?
- How long until we see a test version of our data in the new system?
- What exact data will and will not transfer from our current system?
- What percentage of your migrations require fixes during the validation stage?
- What are the most common problems you encounter – and how do you resolve them?
- Are there any limitations on the data formats or field types you can migrate?
- Will we experience any downtime during or after the migration?
Alto’s answers: 1,600+ migrations across 50+ systems; a dedicated team with 45+ years of combined experience; test data within 48 hours; everything transfers with no restrictions; 90%+ need zero fixes; named scenarios with documented resolutions upfront; no format limitations; zero downtime.
Ask every provider those same questions. The gap in answers will tell you a great deal.

The question every agent on a CRM system should be asking
Not ‘is migration risky?’ – with the right partner, it isn’t. Not ‘will we lose data?’ – with Alto, you won’t.
The real question is: what is staying on your current system actually costing you? In time. In admin. In features you don’t have. In AI capabilities you can’t access. In competitive ground you’re ceding to agencies on better platforms.
The cost of staying is real. It’s just slower and less visible than the cost of moving.
Alto has delivered over 1,600 migrations. They typically go live in 16 days. They take everything. And they’ve been doing this longer, and at higher volume, than anyone else in the UK market.
