1. Key Concepts of AX to D365 Migration

The migration from AX to D365 is not just an update—it’s a complete business transformation. D365 brings cloud scalability, real-time insights, and AI-driven analytics.

Before migration, it’s critical to clean up unused users, data, and old workflows. Training such as MicroSoft Ax Training prepares users to handle these challenges effectively.

2. Why Cleanup is Important Before Migration

Cleanup ensures your system is light, efficient, and error-free. Outdated data or unused modules can cause failures during migration. A clean environment means faster data import, fewer issues, and better system performance after migration.

Also, Microsoft’s latest 2025 updates emphasize cleaner metadata and secure configuration for cloud transitions.

3. Top Cleanup Tasks for 2025

Let’s go step-by-step through the essential cleanup tasks to prepare for migration success.

Step 1: Remove Unused Users and Roles

Inactive users create unnecessary access issues. Remove them before migrating. Audit roles and permissions for compliance.

Step 2: Archive Historical Data

Data older than five years often slows migration. Archive or store it in Azure Blob or Data Lake.

Step 3: Review Customizations

Check which customizations are still needed. Many can now be replaced with built-in D365 features.

Step 4: Clean Master Data

Duplicate customer or vendor records can cause major integration issues. Use data management tools to validate master data.

Step 5: Reconcile Transactions

Ensure your open transactions and balances are correct. This keeps your financial reporting accurate post-migration.

Step 6: Validate Integrations

Third-party integrations must be reviewed for compatibility with D365 APIs.

Step 7: Conduct a Trial Migration

Perform a dry run before going live. It reveals hidden issues early.

To learn these tasks in detail, professionals often prefer Microsoft Dynamics Ax Training in Bangalore as it covers migration best practices hands-on.
