Without traceability, data integration cannot be audited.<\/li>\n  <li><strong>Documented error handling:<\/strong> there is a runbook that defines what to do when each type of data integration flow fails, who receives the alert, and within what timeframe.<\/li>\n  <li><strong>Load tests with real data:<\/strong> the system has been validated with volumes equivalent to production peaks.<\/li>\n  <li><strong>System of record defined:<\/strong> for each critical entity, it is documented which system holds the authoritative version of the data in the data integration flow.<\/li>\n  <li><strong>Active monitoring:<\/strong> there is a dashboard showing the status of each data integration flow in real time, with alerts configured for latency and error rate.<\/li>\n  <li><strong>Rollback plan:<\/strong> if the pipeline fails in production, there is a documented procedure to revert without loss of records or corruption of integrated data.<\/li>\n  <li><strong>Documented compliance:<\/strong> data integration flows that move personal data have the legal basis, applied encryption, and log retention policy on record.<\/li>\n<\/ul><p>If any of these points is blank, <strong>the data integration architecture is not ready for production<\/strong> \u2014 even if it works in the test environment.

When the legacy system does not expose an API, the most effective data integration pattern is Change Data Capture (CDC): it detects changes directly in the database transaction log without modifying the source system. Tools such as Azure Data Factory in incremental mode allow capturing those changes and sending them to Dynamics 365 in near real time. This is the approach we apply when the legacy system has no active support or the vendor no longer exists.<\/p>\n  <\/details>\n  <details>\n    <summary>What is the difference between using Power Automate and Azure Logic Apps to integrate Dynamics 365?<\/summary>\n    <p>Power Automate is oriented toward business users and lower-volume flows, with a more accessible interface and premium connectors available without code. Azure Logic Apps is designed for enterprise data integration orchestration: greater control over execution, better error handling, support for asynchronous patterns with Service Bus, and more scaling options. For critical integrations with legacy systems in production, Logic Apps offers the necessary robustness. Power Automate is the right entry point for secondary flows or teams with lower technical maturity.<\/p>\n  <\/details>\n  <details>\n    <summary>What is dual-write and when should I use it?<\/summary>\n    <p>Dual-write is Microsoft&#8217;s native mechanism for near-real-time bidirectional synchronization between Dynamics 365 Finance &amp; Operations and Customer Engagement applications (Sales, Service). It is the right data integration option when you operate both D365 layers and need customer, product, or order data to be synchronized without additional development. It is not designed to connect Dynamics 365 with external systems \u2014 using it as a bridge to legacy ERPs adds complexity without real advantage.<\/p>\n  <\/details>\n  <details>\n    <summary>How do I avoid duplicating data when two systems can modify the same record?<\/summary>\n    <p>By defining the system of record for each entity before designing the data integration. That means only one system has authority to create or modify each type of data \u2014 the other receives the update as a consumer. If both systems need write capability, you need an explicit conflict resolution policy: for example, &#8220;last writer wins&#8221; or &#8220;D365 takes priority over the legacy system for customer data.&#8221; Without that documented policy, real-time data integration generates inconsistencies that are hard to trace.<\/p>\n  <\/details>\n  <details>\n    <summary>How long does a Dynamics 365 integration project with legacy systems take?<\/summary>\n    <p>It depends on the number of flows, the complexity of the legacy system, and the team&#8217;s maturity. A point data integration with a system that exposes an API can be in production in four to six weeks. A complete data integration project with multiple systems, CDC on databases without an API, and a dedicated middleware layer can take three to six months. The factor that most impacts the timeline is not development \u2014 it is defining business rules: which data is authoritative, what happens when it fails, who approves schema changes.<\/p>\n  <\/details>\n<\/section><section class=\"nseo-sources\"><h2>Sources<\/h2><ul><li><a href=\"https:\/\/www.rishabhsoft.com\/blog\/dynamics-365-integration\" target=\"_blank\" rel=\"noopener\">Dynamics 365 Integration to Unify Systems and Boost ROI<\/a><\/li><li><a href=\"https:\/\/www.microteklearning.com\/blog\/microsoft-dynamics-365\/\" target=\"_blank\" rel=\"noopener\">Microsoft Dynamics 365: The Ultimate Guide in 2026<\/a><\/li><li><a href=\"https:\/\/burq.io\/blog\/erp-integration-methods\/\" target=\"_blank\" rel=\"noopener\">ERP Integration Methods: API vs EDI vs Middleware for D365<\/a><\/li><li><a href=\"https:\/\/burq.io\/blog\/erp-integration-guide-microsoft-dynamics-365\/\" target=\"_blank\" rel=\"noopener\">What Is ERP Integration?
