Argo

v3.3.2CI/CD & App Delivery
Feb 22, 2026

Argo CD v3.3.2 fixes the critical client-side apply migration issue that affected self-managed installations in v3.3.0/v3.3.1, requiring specific upgrade steps for users managing Argo CD with itself.

  • breakingEnable ServerSideApply for Self-Managed Installations

    If you have an Argo CD Application managing your Argo CD installation, you must enable `ServerSideApply=true` sync option on that Application before upgrading to v3.3.2. This is required for the upgrade to succeed and prevents apply migration failures.

  • breakingRemove Temporary ClientSideApplyMigration Setting

    If you previously upgraded to v3.3.0/v3.3.1 and set `ClientSideApplyMigration=false` as a workaround, remove this setting after upgrading to v3.3.2. Keeping it may cause field manager conflicts with other Kubernetes controllers.

  • enhancementSafe Upgrade Path for Previously Affected Users

    Users affected by the v3.3.0/v3.3.1 client-side apply migration bug can now safely upgrade to v3.3.2. Follow the upgrade guide carefully and test the upgrade process in a non-production environment first, especially for self-managed installations.
