Support for OrientDB in Sonatype Nexus Repository has been discontinued, and older versions of Nexus Repository (prior to 3.70.5) are built on an outdated architecture that presents high-severity vulnerabilities and cannot be fully patched. The recommended database for Nexus Repository is now PostgreSQL, which offers better performance and support for modern architectures. Users have two migration options: transition to Sonatype Nexus Repository Cloud, which is fully managed and eliminates database management, or migrate to PostgreSQL while maintaining a self-hosted environment, which requires ongoing maintenance and infrastructure ownership.

Nothing will phase out the CMF Watch app, removing it from app stores on April 3, and users are encouraged to migrate to the Nothing X app. Full functionality of the Nothing X app is expected by July 19, 2026. Users must begin transferring their data now, which will deactivate their CMF Watch app accounts. The Watch 3 Pro, launched in July 2025, features a four-channel heart rate sensor, 131 sports modes, a 1.43-inch AMOLED display, dual-band GPS, and a battery life of 13 days. CMF Watches offer budget-friendly options and have received a million investment from Optiemus to enhance their capabilities. CMF operates independently from Nothing, headquartered in India, and has created around 1,800 jobs.

Microsoft is enhancing PostgreSQL to establish it as a high-performance, scalable, and enterprise-ready open database platform, addressing the limitations of legacy systems like Oracle. Many Oracle customers face rising licensing costs, performance bottlenecks, and scalability issues, prompting them to consider migration. Apollo Hospitals successfully migrated from Oracle to Azure Database for PostgreSQL, achieving a 60% reduction in operational costs and a threefold improvement in system performance. Microsoft has introduced an AI-assisted migration tool to simplify the transition from Oracle to PostgreSQL, automating the conversion of schemas and application code. Azure Database for PostgreSQL offers high performance, scalability, and security, with features like v6-series compute SKUs and SSD v2 storage. Azure HorizonDB, a new cloud-native PostgreSQL service, supports extreme performance demands and is designed for real-time analytics. Microsoft is committed to enhancing PostgreSQL as an open-source database for enterprise workloads, enabling organizations to innovate and become more agile.

Netflix has developed an internal automation platform to migrate Amazon RDS for PostgreSQL databases to Amazon Aurora PostgreSQL, reducing operational risks and downtime for nearly 400 production clusters. The platform allows service teams to perform migrations through a self-service workflow while ensuring processes like replication validation and rollback safeguards are maintained. Database access is managed through a platform-managed layer using Envoy, which standardizes mutual TLS and abstracts database endpoints, enhancing security and efficiency. The migration process starts with creating an Aurora PostgreSQL cluster as a read replica of the source RDS instance, initialized from a storage snapshot and continuously replaying write-ahead log (WAL) records. Validation checks are performed to ensure the replica can handle peak write throughput before cutover. For change data capture workloads, the system coordinates the state of replication slots and pauses CDC consumers to prevent excessive WAL retention. The Enablement Applications team at Netflix successfully migrated databases for device certification and partner billing workflows, addressing issues like elevated replication lag due to inactive logical replication slots. As replication lag decreases, the system enters a controlled quiescence phase, adjusts security rules, and reboots the source RDS instance. Once all transactions are processed and the Aurora replica is ready, it is promoted to a writable cluster, and traffic is rerouted. Rollback capabilities are prioritized, allowing redirection back to the original RDS instance if validation checks fail or anomalies are detected post-promotion. This setup enables seamless restoration without redeployment, and CDC consumers can resume from recorded slot positions if needed.

The migration from NTLM to Kerberos authentication is essential for improving security in Windows systems, but it faces challenges such as legacy systems and hardcoded authentication. Organizations must identify NTLM usage, conduct testing with NTLM disabled, and make necessary adjustments or upgrades to migrate successfully. Ongoing monitoring is crucial post-migration to prevent NTLM from re-entering the network. NTLM is associated with significant security vulnerabilities and has been exploited by various threat groups, making its elimination a priority for organizations despite potential hesitations to invest in the migration process. Transitioning to Kerberos is seen as a strategic security investment.
