Angular Material Upgrade Planner

Angular Material’s major version must match the Angular core major version. Update them together in the same hop, upgrade one major at a time on a branch, and run the app/tests after each hop. Commit a clean tree first.

Angular Material 15 requires the same toolchain as Angular 15: Node 14.20+/16.13+/18.10+ and TypeScript 4.8–4.9.

Update Material alongside the Angular core and CLI so the Material migration schematics for this version run.

ng update @angular/core@15 @angular/cli@15 @angular/material@15

Material 15 refactors all components onto Material Design Components (MDC). DOM structure and CSS class names change, so custom component styles can break. This is the single biggest Material upgrade — budget time for visual QA.

floatLabel="never" is dropped (it only existed on the old form-field appearance). Use matTextPrefix/matTextSuffix for baseline-aligned text and matIconPrefix/matIconSuffix for centered icons. Expect density and typography differences.

The @angular/material/legacy-* packages are a temporary bridge — they are deprecated in v15 and deleted in v17, so plan your migration off them before then.

The update schematic rewrites imports to @angular/material/legacy-* so the app runs on v15 immediately with minimal changes. Then migrate component-by-component to the new (non-legacy) MDC components.

ng update @angular/material@15

Angular Material’s major version must match the Angular core major version. Update them together in the same hop, upgrade one major at a time on a branch, and run the app/tests after each hop. Commit a clean tree first.

Angular Material 16 requires the same toolchain as Angular 16: Node 16.14+/18.10+ and TypeScript 4.9–5.1.

Update Material alongside the Angular core and CLI so the Material migration schematics for this version run.

ng update @angular/core@16 @angular/cli@16 @angular/material@16

Replace @angular/material/legacy-* imports with the new MDC components one component at a time, fixing styles as you go. Use the density and typography mixins (mat.<component>-density) to tune the MDC look. Legacy components are still available this version but go away in v17.

Angular Material’s major version must match the Angular core major version. Update them together in the same hop, upgrade one major at a time on a branch, and run the app/tests after each hop. Commit a clean tree first.

Angular Material 17 requires the same toolchain as Angular 17: Node 18.13+/20.9+ and TypeScript 5.2–5.4.

Update Material alongside the Angular core and CLI so the Material migration schematics for this version run.

ng update @angular/core@17 @angular/cli@17 @angular/material@17

The @angular/material/legacy-* packages are removed in Material 17. A schematic logs a fatal error and blocks the update if your app still imports legacy components — you must finish migrating to the MDC components first. (As a stopgap you can keep Material 16 on Angular 17 until v18.)

Angular Material’s major version must match the Angular core major version. Update them together in the same hop, upgrade one major at a time on a branch, and run the app/tests after each hop. Commit a clean tree first.

Angular Material 18 requires the same toolchain as Angular 18: Node 18.19+/20.11+/22 and TypeScript 5.4–5.5.

Update Material alongside the Angular core and CLI so the Material migration schematics for this version run.

ng update @angular/core@18 @angular/cli@18 @angular/material@18

Define themes with mat.define-theme(), which is based on Material 3 design tokens implemented as CSS custom properties. Configure color, typography, and density dimensions. M2 (mat.define-light-theme) is still supported, so migrate themes when ready.
