Microsoft Dynamics 365 Finance & SCM Data Migration Services

Every Dynamics 365 data migration follows five steps: extract the data from your source system, transform it to match D365’s structure, load it, check that it came through, and validate it against what you exported. The key is repetition. We run those steps with real data in the conference room pilot, again in UAT and a mock go-live, and finally in production, so the go-live run is one your team has already rehearsed.

It depends on your data volume, how many legal entities you’re migrating into, how much history you bring, and how clean the source data is. Because migration runs through every test round, it spans the whole implementation rather than one weekend. We estimate go-live timing early by migrating a subset, such as the first 100 customers and vendors and a point-in-time GL entry. With AMCS, Now Optics completed its finance migration in six months, against a typical 12 to 18.

For Finance & SCM, Microsoft’s standard tool is the data management framework (DMF), built on data entities. AX 2009 customers use Microsoft’s Data Migration Tool, and Customer Engagement apps use the Configuration Migration tool for setup data. Azure Data Factory and SSIS handle complex transformations. For many legal entities, we use AMCS and its Data Migration Accelerator, which imports every data type for every company from one file and posts journals automatically.

It’s the plan that decides, before any data moves, what migrates, how much history you keep, how data is extracted and transformed, how many times you’ll rehearse, and how you’ll prove it worked. A good strategy includes a configuration baseline, mapping rules, a financial dimension plan, real-data testing from the first CRP, and sign-off criteria. Microsoft recommends defining it before the project starts and updating it as the project progresses.

Yes. If you’re on AX 2012 R2 or R3 with the latest cumulative update, Microsoft supports a direct upgrade. AX 2012 RTM and AX 2009 have no direct path; AX 2009 uses Microsoft’s Data Migration Tool, or you reimplement and migrate master data and open transactions. Many companies choose reimplementation to leave old customizations and data behind. Either way, the data is cleaned, mapped, and rehearsed before production.

After every load, we confirm the import succeeded, then check that the count of records migrated matches the count exported, that balances tie to the source, and that every transformation happened correctly. Then a business owner reviews the data and signs off. We run these checks in every test round, not just at go-live, so issues are resolved and documented long before production.

We classify sensitive financial and personal data before it moves, limit migration accounts to the access they need, and protect data in transit and at rest. Records you don’t need are excluded at extraction, so less sensitive data moves at all. After go-live, we review security roles and licensing for every new user, especially after an acquisition, when teams bring different expectations about who can see what.

Usually less than you think. Most companies migrate a time frame based on IRS and compliance requirements, such as the last three or five years, or just balances. Migrating full transaction-level detail is unusual, because volume becomes a real problem. Historical data you don’t migrate can stay in a read-only archive for audits. Database reduction before migrating isn’t always necessary; scoping by compliance usually does the job.

The data management framework is Microsoft’s standard tool for importing and exporting data in Dynamics 365 Finance & SCM. It uses data entities, which group one or more tables into a single object such as Customers or Vendors, organized into data projects and packages. Imports pass through staging tables so errors can be reviewed before data reaches the target. DMF works well for one company; across many legal entities, each import repeats per company.

Cost depends on data volume, the number of source systems, how much history you migrate, how much transformation is needed, and especially how many legal entities you’re moving into. That last driver is where estimates balloon: 8 data types across 10 companies is 80 imports plus with standard tools. If you’re reviewing an estimate that seems out of whack, request a free migration assessment and we’ll show you where it can be streamlined.
