Overview
IONOS is finalizing the transition from MariaDB API v1 to the new MariaDB API v2. The automated migration of your underlying database clusters is handled entirely by IONOS with zero downtime, and your existing connection strings remain unchanged.
However, MariaDB API v1 will be completely deprecated on August 31, 2026. If you manage your infrastructure via our API, Terraform, or SDKs, you must update your tooling to the v2 endpoints before this date to prevent disruptions to your deployment and management workflows.
Deprecation Timeline
- Aug 17, 2026 v1 Cluster Creation Disabled - ✅ Passed
- Aug 24-27, 2026 MariaDB API v1 to v2 Automatic Migration - Upcoming
- August 31, 2026 MariaDB API v1 End of Life - ⚠️ Upcoming
Required Customer Actions
While your databases remain online and accessible during the platform upgrade, you must complete the following updates by August 31, 2026:
- API Integrations: Transition all automated scripts and calls to the MariaDB v2 API endpoint.Infrastructure as Code: Update your Terraform configurations to utilize the new MariaDB v2 provider.
- SDKs: Upgrade any custom application integrations to the latest MariaDB v2 SDK.
- Database Version Upgrades: If you are currently running MariaDB 10.6, you must initiate an upgrade to a supported version (10.11, 11.4, 11.8, or 12.3) before the end of the month, as platform support for 10.6 is ending.
Benefits of the v2 Platform
- Extended Backups: Configure backup retention for up to 365 days, enabling long-term point-in-time recovery.
- Latest Versions: Full support for MariaDB 11.4, 11.8 and 12.3.
- IONOS Observability: Optional integration to closely monitor database performance metrics (Observability usage is billed separately).

Overview
Following the successful automated migration of all DBaaS PostgreSQL clusters to our v2 infrastructure earlier this month, IONOS Cloud is proceeding with the final decommissioning of the legacy PostgreSQL API v1.
The API v1 endpoints will be permanently disabled. Once disabled, any programmatic requests made to the v1 API will be rejected.
Impact & Required Actions
Because your underlying clusters have already been migrated, your databases will experience zero downtime during this API shutdown. However, you must ensure your management tools are updated to avoid disruption to your deployment workflows:
- Endpoint Update: Ensure all scripts, Terraform configurations, and SDKs are pointing exclusively to the regional API v2 endpoints.
- Authentication Switch: PostgreSQL API v2 does not support BASIC authentication. If you have not done so already, you must immediately switch your API and SDK authentication to TOKEN authentication.
API v2 Benefits Reminder
Migrating your tooling to API v2 grants you access to the new platform features:
- Regional Endpoints: Lower-latency API access routed directly to your specific region.
- Observability Integration: Access to forward cluster logs and metrics directly to IONOS Logging and Monitoring.
- SSD Premium Infrastructure: Full management capabilities for the upgraded, high-performance SSD Premium storage tier.
