Question 1

How long does a Vue 3 migration typically take for a mid-to-large app?

Accepted Answer

A well-structured mid-size codebase (50–150 components) usually takes 6–8 weeks to complete with our vue 2 to vue 3 migration services. Large e-commerce or fintech platforms with 300+ components, custom integrations, and legacy patterns may require 3–5 months, especially if zero downtime is a priority.

Question 2

What's the typical cost?

Accepted Answer

It depends on app size, number of custom modules, SSR complexity, and the state of your current codebase. We provide a detailed estimate after reviewing your setup — fill out the form below or book a call to get started.

Question 3

Can migration be done gradually?

Accepted Answer

Yes. With strategies like hybrid rendering, micro-frontends, or isolated module rewrites, we can migrate part of the app to Vue 3 while keeping Vue 2 for the rest. This approach is especially valuable for large codebases where a "big bang" switch would be too risky. You can watch our CTO's talk on granular updates here: https://youtu.be/d452TBxOJw0

Question 4

What does an end-to-end migration process look like?

Accepted Answer

If you're looking to convert Vue 2 to Vue 3 or migrate an existing application, here's how a typical end-to-end process looks: Code & dependency audit — map out migration blockers. Strategy — choose big-bang or phased migration. Environment prep — CI/CD and test setup for both Vue versions if needed. Refactoring — update syntax, APIs, and patterns. Regression testing — automated + manual. Staged rollout — gradual deployment with monitoring. Post-launch support — bug fixes and optimisations.

Question 5

Can your Vue.js migration experts work with our in-house team?

Accepted Answer

Yes. As a Vue.js migration agency, we often work alongside in-house engineering teams and adapt to the setup that is already in place. Depending on your needs, we can help with migration assessment and planning, support your developers during implementation, or take ownership of Vue migration work.

Question 6

Do you give warranties after migration?

Accepted Answer

Yes. As a Vue.js migration firm, we define a warranty period where any migration-related bugs are fixed as part of the original scope.

Question 7

Do you offer post-migration maintenance?

Accepted Answer

Yes. We can act as a support partner for performance tuning, dependency updates, and ongoing Vue ecosystem changes.

Question 8

What if we want to validate the application after a Vue 2 to Vue 3 migration?

Accepted Answer

That is a common next step for teams that want extra confidence after release. In addition to migration support, we can also help with a focused Vue.js code audit to review code quality, architecture, performance, and any remaining migration-related issues.

Question 9

Is it urgent for all projects to upgrade from Vue 2 to Vue 3?

Accepted Answer

No. If your app is internal-only, dependencies are stable, and there are no compliance or security requirements, you can delay. But for public apps with regular updates, external integrations, or data privacy requirements, the cost and complexity of migration grow the longer you wait.

Question 10

When is it not a good time to migrate to Vue 3?

Accepted Answer

If the product will be retired or rebuilt within a year, is an internal tool with no compliance or security exposure, or is blocked by critical Vue 2-only dependencies, migration can wait. As we explain in our Vue 3 migration guide, it's also better to delay if you have no automated test coverage, no available team capacity, or are in the middle of a critical release or peak business season.

Question 11

What are the real risks for a large-scale Vue 2 migration?

Accepted Answer

Breaking mission-critical flows (checkout, payment, onboarding); dependency incompatibility with key UI kits or API wrappers; gaps in test coverage leading to production regressions; deployment complexity when rolling out changes to large teams or distributed environments.

Question 12

What are the most common Vue 3 migration challenges?

Accepted Answer

The most common issues we encounter: third-party library compatibility (especially UI kits like Vuetify or PrimeVue in apps with 200+ components), state management migration from Vuex to Pinia, legacy Options API patterns that need gradual refactoring, and dependency lock-in where key packages haven't released Vue 3-compatible versions. For e-commerce and fintech apps, the additional challenge is keeping critical flows — checkout, payments, user sessions — stable throughout the migration. This is why we start every project with a dependency and architecture audit before committing to scope.

Question 13

Does Vue 3 deliver measurable performance improvements?

Accepted Answer

In most cases, yes — especially for apps with heavy reactivity use or large component trees. Vue 3's Proxy-based reactivity reduces overhead, and tree-shaking cuts bundle size. On high-traffic sites, that means faster TTFB, better Core Web Vitals, and lower CPU usage on mobile devices.

Question 14

Do we need to migrate to Nuxt 3 as part of a Vue 3 upgrade?

Accepted Answer

Not necessarily. If your app already uses Nuxt 2, you can migrate Vue first and plan the Nuxt upgrade separately. However, Nuxt 3 is built on Vue 3, so eventually you'll need to upgrade both to keep framework, dependencies, and tooling in sync. As we explain in our Nuxt migration blog, SEO-heavy or SSR apps may benefit from combining both migrations in one project to reduce duplicated work.

Question 15

Is it worth adopting the Composition API during migration?

Accepted Answer

In most cases, yes. As a vue.js consulting agency we recommend adopting the Composition API — it offers better code organization, easier logic reuse, and native TypeScript support — benefits that compound over time in large applications. If your codebase is huge, you can mix Options API and Composition API, converting only new or refactored modules, to keep migration manageable.

Question 16

Can we mix Composition API and Options API in Vue 3?

Accepted Answer

Yes. Vue 3 fully supports using both APIs in the same project. This is a common approach during a migrate from Vue 2 to Vue 3, as it allows you to keep existing components in the Options API while writing new or refactored ones with the Composition API. This reduces migration risk, spreads refactoring effort over time, and lets the team adopt new patterns gradually without halting feature development.
