How to migrate your paging tool without breaking your team

Engineering teams often delay migrating their on-call and paging systems until it's absolutely necessary due to the potential disruption and retraining involved. Common triggers for such migrations include vendor end-of-life, contract renewals, or scaling issues with existing setups. Successful migrations require strategic planning, often following a four-step framework: taking a comprehensive inventory of current systems, enlisting change agents, forming a project team with clear roles, and developing a realistic timeline. The inventory process involves identifying and evaluating all current schedules, policies, and tools, which helps set realistic expectations and proves ROI. Engaging change agents, including those most affected by current inefficiencies, influential leaders, and potential detractors, can facilitate smoother adoption. Building a project team with a variety of roles ensures coverage of necessary tasks throughout the migration. The timeline should allow for overlap between old and new systems to account for unforeseen issues. A critical aspect often overlooked is the service catalog and ownership models, which help maintain a centralized source of truth and streamline incident management. Ultimately, the migration process offers the opportunity to not just replicate existing systems on new software but to improve workflows and enhance team efficiency.
