Software Architects and Technical Leads
Planning a legacy system migration to a modern Single Instance Solution
Use cases
About
The SIS mind map template provides a structured framework for managing a Single Instance Solution migration project, specifically designed for engineering teams moving from unreliable legacy systems like Apprenda. This 96-node cheat sheet covers the entire project lifecycle, from initial INFORMATION gathering to technical execution. It outlines critical project constraints such as the 5 months timeline and the involvement of 2 developers. By centralizing technical requirements and business objectives, the SIS template ensures that teams can effectively Remove Apprenda Cloud while maintaining tenant support. The document is organized into logical workstreams including persistence layers, codebase modifications, and deployment strategies, making it an essential tool for software architects and project managers overseeing complex infrastructure transitions.

Frequently asked questions
The SIS (Single Instance Solution) template is designed to guide software development teams through the migration of legacy cloud infrastructure to a more stable, single-instance architecture. It helps track requirements, work scope, and risk mitigation in one visual space.
It includes specific nodes for Persistence (MS SQL, MongoDB), Logging, and Codebase management. This allows architects to map out how to replace internal log providers and implement new Platform Providers without disrupting existing business logic.
Yes, the template features a dedicated SCHEDULE section divided into Phase 1, 2, and 3. You can easily edit these nodes to include specific dates, task owners, and custom milestones relevant to your team's velocity.
Absolutely. The RISK branch includes a comprehensive assessment structure covering SEVERITY, PROBABILITY, and MITIGATION APPROACH, ensuring that technical hurdles are identified and addressed before they impact the project timeline.
