What measures have you taken to transition to a new technology stack?

When transitioning to a new technology stack, I usually take the following steps:

1. Analysis and Planning — I study the new stack, its capabilities and limitations, and assess risks and benefits.
2. Team Training — I organize training sessions, seminars, or courses so that the team understands the new technologies.
3. Pilot Project — I implement a small project or module on the new stack to test hypotheses and identify issues.
4. Gradual Transition — I migrate functionality step-by-step to minimize risks and maintain stability.
5. Automation and Testing — I implement CI/CD, write tests to ensure quality.
6. Documentation — I create documentation on the new stack and processes.

This approach helps to smoothly and safely transition to new technologies, minimizing downtime and errors.
