Software Architects and Technical Project Managers
Planning a complex legacy system migration to a single instance architecture
Use cases
About
The SIS (Single Instance Solution) mind map template is a comprehensive project planning framework designed for software engineering teams migrating legacy cloud infrastructure. It covers critical migration phases, technical requirements, and risk assessment across 100 nodes of structured data. This SIS template serves as a technical SIS cheat sheet for developers moving from unreliable platforms like Apprenda to more stable architectures. The structure is anchored by six core pillars: INFORMATION, GOALS, Work Scope, SCHEDULE, RISK, and Questions. It specifically addresses technical transitions such as moving to MS SQL and MongoDB persistence layers while maintaining tenant support and minimizing business logic disruption. By using this SIS mind map, project leads can track specific requirements like the '3rd Party auth system' and manage a '5 months' development timeline with a dedicated '2 developers' team.
Terms and ConditionsWhen to use this template
Backend Engineering Teams
Conducting a technical discovery phase for a new platform provider implementation
CTOs and Product Owners
Presenting a multi-phase development roadmap to stakeholders for infrastructure budget approval
How to use this template
Step 1
Import the SIS file
Open the .xmind file in Xmind desktop or web app to view the full 100-node migration structure.
Step 2
Define your technical scope
Navigate to the 'Work Scope' branch and replace the placeholder MS SQL or MongoDB nodes with your specific technology stack.
Step 3
Set project milestones
Update the 'SCHEDULE' section by dragging nodes into the appropriate Phase or Milestone to align with your team's sprint velocity.
Frequently asked questions
This template includes a full project breakdown for a Single Instance Solution migration. It features sections for stakeholder information, technical goals, detailed work scope (including logging and event buses), a three-phase milestone schedule, and a comprehensive risk management framework.
Start by defining your migration drivers in the 'INFORMATION' branch. Use the 'Work Scope' section to list specific database and codebase changes, then map these to the 'PHASE 1' through 'PHASE 3' schedule to ensure a logical rollout of services.
Yes, every node in this SIS template is fully editable. You can customize the 'REQUIREMENTS' to fit your specific team size, adjust the 'Work Scope' for different tech stacks, and expand the 'Questions' branch as new technical challenges arise.
The 'RISK 1' structure is a template for proactive problem-solving. It allows teams to document the 'IMPACT', 'SEVERITY', and 'PROPOSED SOLUTIONS' for any technical threat, ensuring that mitigation strategies are decided before issues occur during the migration.
