Ionic Version Upgrade Services
Stuck on Ionic 4 or 5, and stuck on an old Angular version because of it? Multi-version Ionic upgrades are riskier than they look when a generalist underestimates them. We scope the full version gap before we quote it.Accurate scoping is the differentiator, not speed.

Stuck On An Old Ionic Version
Multi-version upgrades get postponed because they look risky. Usually they're just unscoped.
Who This Is For
Your app still runs Ionic 4 or Ionic 5
You're blocked on an old Angular version because of Ionic
A previous developer warned that upgrading Ionic 'might break everything'
New Ionic features and plugins require a version you're not on
You want the upgrade quoted accurately, not underestimated
Problems We Solve
Locked to an Old Angular Version
Ionic's supported Angular range means you can't upgrade Angular without upgrading Ionic first, and vice versa.
Deprecated Components Everywhere
Ionic 4 and 5 components have since been replaced or restructured, and your app depends on the old ones.
Every Quote So Far Has Been Wrong
Generalist estimates treat a multi-version jump like a single upgrade, then blow past the timeline.
Security Patches You're Missing
Versions this old no longer receive security fixes, a growing liability the longer it's postponed.
How We Scope and Run an Ionic Version Upgrade
We map the full version gap before we quote it, so the timeline holds once work starts. 3-6 weeks for a single major version, longer for multi-version jumps
Compatibility Audit
We map your current Ionic, Angular, and Capacitor versions against the target, and list every breaking change across each version boundary in between.
You'll Receive:
Dependency & Angular Alignment
Where Ionic's target version requires a newer Angular release, we upgrade Angular first, since Ionic tracks Angular's own release cadence.
You'll Receive:
Component & API Migration
We update deprecated Ionic components, adjust for lifecycle changes, and fix styling that assumed an older Ionic CSS structure.
You'll Receive:
Regression Testing & Store Release
Full regression pass on iOS and Android, then a store release once the upgraded build is verified stable.

Why Multi-Version Ionic Upgrades Get Underquoted
A jump from Ionic 4 or 5 to the current release crosses several major versions, not one.
Why multi-version Ionic upgrades get underquoted:
Each Major Version Has Its Own Breaking Changes
Jumping from Ionic 4 or 5 to the current release means crossing several major versions, each with its own deprecated components and API changes, not one upgrade.
Angular Moves the Goalposts
Ionic Angular's supported version tracks Angular's own releases, so an old Ionic app is often also stuck on an old Angular version that needs upgrading first.
Component APIs Change Between Majors Too
Angular isn't the only dependency that moves. Ionic's own components get restructured between major versions, and those changes have to be found and fixed by hand, not resolved by a dependency bump.
We Quote After the Audit, Not Before
We scope the upgrade against your actual codebase and component count, not a generic estimate.
An Ionic App We've Kept Current for Years
Summon has stayed on a supported Ionic version through years of production use. That's the same discipline we bring to upgrade engagements.
Scaling from 100 to 450+ Active Locations
Divtechnosoft built and has continuously maintained Summon, a paperless valet management platform on Ionic and Capacitor, since its first release. Keeping it on a current, supported version is part of how it has stayed reliable across 450+ venues.
"Divtechnosoft built our entire valet platform end-to-end, not just pieces of the code. The team always articulates options and solutions in a very clear and concise way. We are happy to be working with such a responsive, fast and reliable group of high quality engineers."

Beyond the Version Upgrade
An upgrade solves version drift. These cover what's often bundled with it.

Maintenance & Support
After the upgrade, a retainer keeps the app current instead of drifting again.
Cordova to Capacitor Migration
Still on Cordova? That migration is usually worth doing alongside a version upgrade.
