    Brief

    Transport for London (TfL) is seeking a specialist support partner to provide 24/7/365 break-fix support and comprehensive technical expertise for a portfolio of legacy infrastructure technologies that are no longer fully supported by their original vendors. The current infrastructure estate includes legacy versions of Microsoft Windows Server, SQL Server, Oracle, Solaris and Red Hat platforms. Key service requirements include: operational support and incident management, service desk provision with escalation management, comprehensive reporting, cybersecurity compliance and risk management, and support for eventual migration of services to modern supported platforms. TfL requires a scalable service that adapts as the legacy estate evolves over time. Suppliers must demonstrate robust operational processes, proven ability to mitigate risks associated with unsupported technologies, and commercial flexibility through both managed service and consumption-based support models. This is an opportunity for suppliers to demonstrate market capability, innovative delivery approaches, flexible commercial structures, and expertise in supporting critical legacy infrastructure within a highly regulated operational environment. TfL is actively seeking to understand available market solutions and partner approaches for managing legacy technology dependencies.
