Before you switch
What decides whether a HubSpot migration goes smoothly.
A readiness guide for established B2B companies moving ot HubSpot. Eight things you can assess before anyone touches your systems.
How much history you are bringing
The volume and age of your data is the single biggest driver of migration effort. Two clean years in a simple CRM is a different project from twelve years of contacts, deals, custom objects, and the workarounds that piled up across all of it. And it is not only size — it is how much of that history you actually need live in the new system versus archived.
How many years of records are in your current system, and how much does your team reference in a normal quarter?
How custom your current build is
A near-default Pipedrive or Mailchimp setup moves quickly. A Salesforce instance with custom objects, validation rules, Apex, and years of admin decisions is another undertaking — every piece of customization was a decision someone made for a reason. The trap is assuming custom equals important: some of it is load-bearing, some is a workaround for a problem you no longer have.
Could someone on your team list the custom fields, objects, and automations — and say why each one exists?
How many integrations are wired in
Your CRM rarely sits alone — website, accounting, support desk, calendar, maybe a data-enrichment tool or two. Each connection has to be re-established and tested in HubSpot, and each is a place where a quiet handoff can break without anyone noticing for weeks. The integrations you forget are the ones that cause trouble.
Can you name every tool connected to your CRM, including the ones set up by people who have since left?
Whether anyone documented the automations
This is the one that catches established companies. Years of workflows, sequences, lead routing, and lifecycle logic, built incrementally and rarely written down. When that is the situation, the first real work of a migration is not moving anything — it is reconstructing what the current system actually does. Companies that have it documented move faster and cheaper.
If the person who built your automations left tomorrow, could someone else explain what they do?
How your team will be brought along
The platform almost never decides whether a rollout sticks. The team does. The team most likely to resist is the one that was not consulted, not trained, and did not see the new system make their day easier in the first month. This is the part you can influence most before anything technical happens.
Do you know which people will champion the move and which will resist it — and why?
What you are actually trying to fix
“We need a better system” is a feeling, not a spec. The migrations that go well start from specific problems: leads dying in the gap between marketing and sales, reporting leadership stopped trusting, customer context that disappears when a deal moves to support. When the problems are named, the build has a target.
Can you name the three specific problems that made you start looking at HubSpot?
Who owns this internally
A migration needs one person inside the company who can make decisions, answer questions, and keep things moving — not someone who does the work, but someone who owns the outcome and has the authority to settle the calls that come up. When that person exists and has the time, projects move. When it is everyone's responsibility and no one's priority, it stalls in the gaps between people.
Is there one person who will own this move, with the time and authority to make decisions on it?
Whether you can run both systems in parallel
The safest migrations keep the old system live alongside the new one until the new one is verified. That takes the willingness to pay for both for a few weeks and the discipline not to cut over until the data and workflows are confirmed working. A short overlap is cheap insurance against an expensive mistake.
Are you prepared to run both systems in parallel for a few weeks rather than cutting over immediately?

This guide cannot give you a real timeline or number — that depends on what is actually inside your current system. The only way to know is to look at it together. Bring the gaps you found; those are the parts worth talking through first.
