Frequently Asked Questions

What are the main challenges when consolidating legal entities in Dynamics 365?

The primary challenges include mapping diverse main accounts into a single structure, aligning differing financial dimensions, eliminating intercompany transaction balances correctly, and ensuring the continuity of historical reporting across the merged entities.

Can I migrate historical AX 2012 data directly into a consolidated D365 entity?

Migrating historical data directly into a newly consolidated entity is highly complex and generally discouraged. Instead, historical data is often kept in a data warehouse (like Azure Data Lake) for reporting, while only opening balances and active transactions are brought into the new Dynamics 365 environment.

How should intercompany balances be handled during the migration?

Intercompany balances between the three entities must be carefully audited and either eliminated or meticulously mapped to the new consolidated account structure. Failure to do so can result in double counting and inaccurate financial statements in the new system.

Do I need a certified Microsoft Partner for an AX 2012 to Dynamics 365 migration?

Yes. Given the profound complexity of merging legal entities, redesigning financial dimensions, and upgrading from AX 2012, engaging a certified Microsoft Dynamics 365 Partner is strongly recommended to ensure a compliant, supported, and successful migration.
