I once integrated a new CRM at work. We planned carefully, tested thoroughly, and rolled out gradually. Some syncing issues arose, but we caught them fast. Key points for smooth integration: Plan carefully: Map out how new app fits with existing parts. Test thoroughly in a separate environment. Use APIs to connect new and old systems. Gradual rollout to small groups first. Monitor closely and fix issues quickly. Train users on the new app. Keep old system running until new one is stable. Update all documentation. Have a rollback plan ready. Schedule updates for minimal user impact. This approach ensures a smooth transition, minimizes disruptions, and allows for quick problem-solving.

Com planejamento cuidadoso, testes rigorosos e implementação gradual, dá pra integrar um novo aplicativo web ao sistema existente sem interrupções

Before you begin the integration process, it's essential to have a detailed plan in place. You should map out how the new web application will fit into your existing architecture, identifying potential compatibility issues and dependencies.

-We need to make sure that any existing bookmarks of old application is getting redirect to new application. If such page does not exists then we should show proper page/message to the end user. Redirection rules are set properly. -Also, if there is any RSS feeds we need to make sure that is working correctly.

Testing plays a crucial role in ensuring the smooth integration of components in any application. By incorporating different testing practices (such as Regression; Integration; Performance and E2E testing to name a few), you can identify and address integration issues early, reduce the risk of bugs and defects on go live, and deliver a reliable and seamlessly integrated application to users. Integration testing verifies that the different components of the web application work together as expected. By retesting previously working components, regression testing helps ensure that new integrations do not negatively impact existing system.

Start by setting up a controlled testing environment that mirrors your production system as closely as possible. This allows you to simulate the integration and observe how the new web application interacts with your existing system.

Keep all stakeholders informed about the progress, challenges, and changes that might affect them. Regular updates can help manage expectations and reduce resistance to change.

1. Manage Data Transitions 2. Ongoing Performance Monitoring 3. Enhance Stakeholder Involvement 4. Refine Through User Feedback

When deploying web applications, using live trials can be a great way to gather feedback and test new features on the existing system before a full release. For example, giving access to the new functionalities to a limited number of selected users and allowing to monitor and gather feedback in a controlled environment.

Consider a phased deployment approach. Start by rolling out the application to a small group of users or a single department before making it available system wide.

Perform gradual rollouts or deployments, creating releases. When adding new functionalities in production, ensure that they are well tested by the team, firstly ensuring unit, integration, (e2e if possible) and manual tests by the team. But most importantly, if it is a large release or rollout, there are some forms such as Canary Release, where you define a percentage of how many users will fall into the new flow or functionality that was implemented, preventing all users from seeing it, in order to validate the that was done. Another way is to release small features like Feature Toogle. Concept where you can release the functionality in production through true or false (Example: Faster).

Monitoring is crucial to ensure that the new web application performs as expected within the existing system. Set up monitoring tools to track performance metrics, error rates, and user engagement.

After implementation, try to monitor the health and possible errors that may occur in your end-to-end application. Monitor your application through platforms such as DevTools' own LightHouse, bringing WebVitals metrics. TrackJS, Sentry, Grafana Faro, these tools, to collect errors and configure alarms in your application. For product monitoring, use tools such as Amplitude, Google Analytics, etc... to collect product data and metrics, such as event funnels and user journeys, if nothing was impacted.

In a competitive programmers sarcastic perspective yet a smiling joke sort of way.... Ouch, that is way too complicated and involves way too many people take the risk before you scare your team by looking like your nervous or lack the confidence to take a chance and break some shift to make things better.
