Migrate Vaultwarden to PostgreSQL: Scale for Teams [2026]

Self-hosting Vaultwarden with SQLite can lead to performance issues as the user base grows, particularly due to SQLite's limitations with concurrent writes. Transitioning to PostgreSQL allows for better performance, multi-user support, and enhanced data durability. PostgreSQL supports concurrent connections and row-level locking, making it more suitable for team environments. To migrate from SQLite to PostgreSQL, certain prerequisites must be met, including having an existing Vaultwarden deployment, Docker Engine, a PostgreSQL server, and pgloader installed. The migration process involves backing up existing data, deploying a PostgreSQL container, updating configuration files, and using pgloader to transfer data. A VPS with 2 vCPU and 4GB RAM can support up to 50 users, with larger teams requiring more resources. PostgreSQL also allows for the creation of organizations for shared vault access and the configuration of group policies for security. Regular backups and performance tuning are necessary to maintain optimal operation. Common pitfalls during migration include not stopping the Vaultwarden container before migration, failing to encode special characters in the database password, and neglecting to back up data. Troubleshooting may involve checking connection strings and ensuring the PostgreSQL container is healthy. Advanced configurations can enhance performance and functionality, and understanding the differences between Vaultwarden and Bitwarden's official self-hosted server can aid in decision-making.

Migrate self-managed PostgreSQL to Amazon RDS using the RDS console

Running PostgreSQL on Amazon EC2 requires users to manage operational tasks such as patching, backups, and security. Migrating to Amazon RDS for PostgreSQL or Amazon Aurora PostgreSQL-Compatible Edition offers a fully managed service that automates these tasks, allowing development teams to focus on application development. The migration process uses the auto-migration feature in the Amazon RDS console, supported by AWS Database Migration Service (AWS DMS), which facilitates PostgreSQL-to-PostgreSQL migrations using native tools for accurate schema mapping and faster migration. The migration can be executed using various methods, including pg_dump/pg_restore, manual AWS DMS tasks, or third-party tools, with the RDS console approach being preferred for its reliability and minimal setup effort. AWS DMS supports three replication modes: full load, CDC only, and full load + CDC, with the migration duration depending on database size and network throughput. Prerequisites for migration include having a source PostgreSQL 10.4+ on Amazon EC2, a target RDS for PostgreSQL or Aurora PostgreSQL, proper IAM roles, stored credentials in Secrets Manager, and appropriate networking configurations. Considerations include unsupported objects, potential issues with sequence values, and the need to avoid schema changes during CDC. The migration involves preparing the source database, creating necessary users and permissions, and executing the migration through the RDS console. Post-migration, it is essential to verify data integrity, optimize performance by updating statistics and rebuilding indexes, and implement security best practices such as disabling the DMS user and enforcing SSL/TLS connections. Common troubleshooting errors during migration include permission issues, incorrect WAL levels, and connection refusals, each with specific resolutions. Finally, to avoid ongoing charges, it is recommended to clean up resources created during the migration process, including deleting the DMS migration task, logical replication publications, Secrets Manager secrets, and the target RDS/Aurora instance.
