The Business Central 14 Reimplementation tool is a cloud migration option for customers on Business Central version 14 who want to start fresh in the cloud. Instead of migrating all data and customizations, the tool migrates only essential business data. It's designed for reimplementation projects where you want a clean start without legacy customizations or historical transactions.
Important
- This is a preview feature.
- Preview features aren’t meant for production use and might have restricted functionality. These features are subject to supplemental terms of use, and are available before an official release so that customers can get early access and provide feedback.
When to use this tool
Choose the Business Central 14 Reimplementation tool when:
- You're on Business Central version 14 and want to move to the cloud
- You want to leave behind obsolete customizations and start fresh
- You don't need historical ledger entries in your new environment
- You're doing a reimplementation rather than a lift-and-shift migration
Choose the standard full data migration tool (Dynamics 365 Business Central current version or Dynamics 365 Business Central earlier versions) when:
- You need all historical data and transactions
- You want to preserve existing customizations
- You're on a version other than BC14
Note
The Business Central 14 reimplementation tool only supports Business Central version 14. For other versions, use the standard cloud migration.
What data is migrated
The reimplementation approach prioritizes a clean system by migrating only essential business data needed to operate going forward.
Note
Data is moved by migrators, which are modular components that transfer defined sets of business data from the source environment to Business Central. The tool currently includes more than 40 migrators, with more expected over time.
The following table shows the types of data that are migrated and examples of each type.
| Data category | Examples |
|---|---|
| Master data | Customers, vendors, items, G/L accounts, dimensions |
| Transactional data | Open sales orders, open purchase orders |
| Opening balances | G/L balances, customer balances, vendor balances, item inventory |
| Setup data | Company information, posting setup, number series |
Legacy C/AL customizations and their extension data aren't migrated. A defined subset of historical posted entries (for example, posted G/L entries and posted sales invoices) is included; arbitrary ledger history beyond that subset isn't migrated by default. If you want to migrate specific customizations and extension data, learn more in Extend the tool.
