Migrate Google Cloud SQL for PostgreSQL to Amazon RDS and Amazon Aurora using pglogical

PostgreSQL is a popular open-source relational database used by enterprise developers and startups, enabling rapid prototyping and supporting mission-critical applications. Amazon RDS for PostgreSQL and Amazon Aurora PostgreSQL-Compatible Edition facilitate easy setup, operation, and scaling of PostgreSQL deployments in the AWS Cloud, automating administrative tasks like software installation, storage management, and backups. The pglogical extension, compatible with PostgreSQL versions 9.4 and higher, allows for asynchronous replication and is supported on RDS for PostgreSQL and Aurora PostgreSQL from version 12. It uses a publisher/subscriber model for logical streaming replication. To migrate a PostgreSQL database from Google Cloud SQL to RDS for PostgreSQL or Aurora PostgreSQL, users must configure the primary database in Cloud SQL, create a PostgreSQL user with replication privileges, enable logical replication parameters, and create the pglogical extension. The RDS instance also requires a special user for replication, enabling logical replication parameters and creating the pglogical extension. Known limitations of pglogical include the inability to replicate primary key changes directly, the need to manually transfer extensions, and the lack of support for materialized views and large objects. Workarounds involve using surrogate keys for primary keys, manually creating extensions, and converting large objects to bytea columns or storing them in Amazon S3. DDL statements are not automatically replicated, but can be queued using the pglogical.replicate_ddl_command function.

KDE appeals to Windows 10 ‘exiles’

KDE has launched a campaign called "KDE for Windows 10 Exiles" in response to the end of support for Windows 10, which will occur on October 14. The campaign warns users that while Windows 10 will still function after this date, the lack of updates will lead to performance and security declines, increasing risks of hacking. Users face a choice between switching to the Long Term Servicing Channel, paying for extended security updates, or upgrading to Windows 11, which many are reluctant to do due to various reasons, including corporate policies and hardware incompatibility. KDE advocates for transitioning to Linux, specifically its Plasma Desktop environment, emphasizing its user-friendliness and visual appeal. While installing Linux has become easier, KDE advises users to seek help from Linux enthusiasts for a smooth transition. Once installed, KDE claims users will experience fewer data collection issues and no viruses, although users must remain vigilant against Linux malware. It is important to note that while support for many versions of Windows 10 ends on October 14, Microsoft 365 applications on Windows 10 will continue to receive security updates until 2028.

Streamline code conversion and testing from Microsoft SQL Server and Oracle to PostgreSQL with Amazon Bedrock

Organizations are transitioning from legacy database systems like Microsoft SQL Server and Oracle to open-source alternatives such as PostgreSQL to reduce costs and enhance scalability. This migration process involves several steps, including schema conversion, business logic transformation, data migration, application changes, and performance tuning. Amazon Bedrock aids this process by automating schema and code conversion, data transformation, identifying code compatibility issues, and generating test cases for validation. The migration challenges include adapting database objects to PostgreSQL's syntax, converting stored procedures and functions, executing ETL processes for data accuracy, modifying application code, and optimizing performance. Amazon Bedrock utilizes generative AI to simplify these tasks, significantly reducing manual effort and errors. An example of code conversion from Microsoft SQL Server to PostgreSQL is provided, illustrating how to convert a stored procedure into a PostgreSQL function while generating corresponding test cases. The process involves using the Amazon Bedrock chat interface to submit prompts for conversion and validation. To support the migration, table creation scripts for the Employees and SalaryUpdateLog tables are included, along with test data that covers various employee scenarios. This data allows for comprehensive testing of the converted function, ensuring it correctly applies salary updates based on specified criteria.

Microsoft is done being subtle – this new tool screams “upgrade now”

Microsoft is encouraging users to transition from Windows 10 to Windows 11 as the end of support deadline approaches. To facilitate this upgrade, Microsoft has introduced Windows Backup for Organizations, a tool designed to streamline backups and assist businesses in migrating to Windows 11. This tool, announced at Microsoft Ignite in November 2024 and currently in limited public preview, helps organizations back up and restore Windows settings during device resets or reimaging. It aims to reduce troubleshooting, ensure smoother transitions, and enhance productivity by minimizing downtime. To use this tool, systems must be Microsoft Entra joined, and organizations need an active Microsoft Intune test tenant with Intune service administrator permissions. As of April 2025, Windows 10 holds a 52.9% market share, while Windows 11 has 43.7%. Microsoft must upgrade a significant portion of its user base by the deadline or encourage enrollment in the Extended Security Updates program.

Upgrading to Windows 11 just got easier – Microsoft introduces a new business backup tool

Windows has introduced a new backup tool for organizations, currently in limited public preview, designed to assist in backing up Windows settings during the resetting or reimaging of user devices. This tool supports both Windows 10 and Windows 11, facilitating smoother migration to Windows 11. It was announced at Microsoft Ignite in 2024 and aims to reduce migration overhead and user disruption. Organizations must operate Microsoft Entra joined Windows systems, have an active Microsoft Intune test tenant, and possess Microsoft Intune service administrator permissions to participate in the preview. Additionally, Microsoft offers an Extended Security Updates (ESU) program for businesses unable to upgrade to Windows 11 before Windows 10's end of support on October 14, 2025. Microsoft has also introduced a feature for developers that allows software to seek updates via Windows Update for a more unified app update experience.

Windows 10 relocation assistance with “Windows Backup for Organizations”

Microsoft is launching a public preview of "Windows Backup for Organizations" to facilitate the migration from Windows 10 to Windows 11. This tool allows for the backup of settings from Windows 10 and Windows 11 PCs and enables restoration on devices integrated with Microsoft Entra. The initiative aims to streamline the migration process as Windows 10 support ends on October 14. Devices must be "Microsoft Entra joined" or "Microsoft Entra hybrid joined," running a supported version of Windows 10 or 11, with full functionality requiring Windows 11 22H2 or newer, Microsoft Entra integration, and active Microsoft Intune test tenant and administrator rights. Interested participants can apply through a designated form. Additionally, Microsoft introduced a migration assistant within the Insider Beta preview of Windows 11 to simplify transferring files and settings from old PCs to new ones.
