Django 5.1 to 5.2 LTS or 6.0 — when and how should I migrate?

Decide whether existing Django 5.1 apps should move to 5.2 LTS or 6.0 after 5.1 left mainstream support on April 2, 2025.

Upgrade to Django 5.2 LTS unless you're already on Python 3.12+ and ready to absorb 6.0 changes now.

Upgrade to Django 5.2 LTS

Django 5.2 is the current LTS release and, as of 2026-04-03, the supported-versions table shows 5.2 LTS supported through April 2028. Django 5.1 is already unsupported: mainstream support ended on April 2, 2025 and extended support ended on December 3, 2025. Django 5.2 supports Python 3.10 through 3.14, so it preserves compatibility for apps not yet ready for Python 3.12+. The main blocker-level upgrade caveats from 5.1 are that Django 5.2 drops PostgreSQL 13 support and changes the default MySQL connection charset to utf8mb4.

When to choose

Use this when you want the longest supported landing zone with the fewest forced platform changes. It is the safer default if the app or its dependencies still rely on Python 3.10 or 3.11, or if you want to defer 6.0-only breaking changes.

Tradeoffs

Longest support window and lower immediate migration pressure, but you take a feature release that already started new deprecations and you still need another framework upgrade before April 2028.

Cautions

Check database prerequisites before the app upgrade: PostgreSQL 13 is no longer supported in 5.2. If you rely on legacy MySQL utf8/utf8mb3 behavior, validate charset-sensitive code and data handling because new connections default to utf8mb4.

Upgrade directly to Django 6.0

Django 6.0 is the latest official release line and, as of 2026-04-03, the downloads page lists 6.0.3 as current. The supported-versions table shows Django 6.0 receives mainstream support until August 2026 and extended support until April 2027, which is a shorter runway than 5.2 LTS. Django 6.0 supports only Python 3.12, 3.13, and 3.14, and the release notes explicitly state that 5.2.x is the last series supporting Python 3.10 and 3.11. Blocker-level breaking changes include dropping MariaDB 10.5 support and changing the default DEFAULT_AUTO_FIELD to BigAutoField.

When to choose

Use this when you are already on Python 3.12+ and want the newest Django features now rather than another short-term hop later. It is the better choice if your team can absorb framework and platform changes quickly and does not need an LTS support horizon.

Tradeoffs

You skip an intermediate framework hop and standardize on the newest branch, but you accept a shorter support window and stricter runtime/database requirements than 5.2 LTS.

Cautions

Do not choose 6.0 if the app, deployment base image, or dependencies still require Python 3.10 or 3.11. Review release-note compatibility issues carefully for MariaDB 10.5 removal, DEFAULT_AUTO_FIELD behavior, and custom ORM expression code that must return params as a tuple.
