Website Migration Estimator
Platform Migration Estimator for Replatforming Projects
If you are planning a Webflow, Shopify, WordPress, Bubble, or legacy-platform migration, this estimator gives you a fast read on migration timeline, downtime risk, data complexity, and whether the move looks low-risk or high-risk.
What this website migration estimator helps you answer
Migration timeline
Estimate how long a replatforming project may take based on page count, integrations, target stack, and downtime requirements.
Downtime and cutover risk
See whether your platform migration likely needs a simple move, a phased rollout, or a more careful parallel-run cutover strategy.
Scope before you commit
Use the result to decide whether the move is closer to a straightforward website migration, a headless commerce migration, or a deeper platform rebuild.
Best fit
Use this estimator if you are planning to migrate off a platform you have outgrown
Your current platform is becoming the bottleneck
Use it if Webflow, WordPress, Shopify, Bubble, or another platform is starting to limit performance, flexibility, scalability, or operational control.
You need to know migration risk before asking for quotes
If you are comparing a headless commerce move, a custom web app migration, or a modern stack rewrite, this estimator helps frame the scope before procurement starts.
Downtime, data migration, or integrations make the move feel risky
Use it when the hard part is not just rebuilding pages, but preserving live traffic, customer data, and operational workflows during the transition.
FAQ
Platform Migration Estimator FAQ
How long does a Webflow, Shopify, WordPress, or Bubble migration usually take?
It depends on page count, integrations, data migration, and how much downtime you can tolerate. A small website migration may be measured in weeks, while a more complex replatforming project can take months once data, commerce flows, and cutover planning are involved.
When does a platform migration become high-risk?
Risk increases when the current site must stay live, when there are many integrations, when custom data must be migrated, or when the target platform introduces architectural complexity such as headless commerce or a full modern-stack rewrite.
Can I migrate my website without downtime?
Sometimes, yes - but zero-downtime migrations usually require more planning, staging, and cutover discipline. This is exactly why the estimator asks about downtime tolerance.
Should I move to headless commerce or a custom web app?
That depends on why you are migrating. If the goal is flexibility, performance, or complex buyer flows, headless or custom may make sense. If the problem is simpler, a lighter migration path may be cheaper and safer. The estimator is meant to help frame that decision early.
Does this estimator include data migration and integrations?
Yes. The result factors in page count, integration count, custom data, and downtime requirements because those are usually the biggest drivers of migration scope and risk.
What should I do after I get the result?
Use the result to decide whether you need a migration review, a phased scope pack, or a deeper architecture conversation before moving off the current platform.
