Why Clean Data Matters Before Moving to Business Central
Data migration affects almost every part of your ERP project. Clean data makes testing smoother, reduces manual rework, and builds trust in the new system.
Poor data slows configuration, causes posting errors, and makes training more frustrating for users.
Business Central works best when the information behind it is accurate, consistent, and easy to understand.
There are clear benefits to preparing and cleaning your data before you migrate.
• Clean data improves search results and user confidence.
• Accurate records support correct balances and totals.
• Duplicate entries create conflicts and must be fixed by hand.
• Inconsistent formats trigger failed imports.
• Outdated or inactive records make reports harder to read.
• Properly structured data fits better into standard Business Central workflows.
Taking time to clean your data protects your project timeline and reduces risk.
A clean dataset makes Business Central feel organized from day one and helps your team adopt the system with less stress.

Steps to Prepare Data for Business Central
Preparing your data is one of the strongest ways to support a smooth migration.
These steps help you organize your information, remove clutter, and create a clean dataset that loads correctly into Business Central.
Each step builds on the last and improves the quality of your final import.
1. Review Your Master Data
Master data sits at the core of your system. This includes customers, vendors, items, and your chart of accounts.
Review each group carefully. Merge duplicate records, remove entries you no longer use, and update missing contact details. Check that email addresses, phone numbers, and names are current and correct.
Clean master data improves day to day work and reporting. Users find the right records faster, and Business Central can process transactions without confusion caused by old or incorrect entries.
2. Standardize Key Fields
Standard formatting helps Business Central accept and use your data correctly. Look for fields that should follow a single format across all records.
• Street and city fields in addresses
• Phone number formats
• Units of measure
• Item names and descriptions
• Payment terms and methods
• Account names and codes
• Customer and vendor naming rules
Consistent formatting supports smoother imports and clearer reports. It also gives users a more predictable experience when they search, filter, or sort records in Business Central.
3. Decide What to Migrate and What to Archive
Not all data needs to move into your new system. Old quotes, inactive customers, vendors you no longer use, and items you no longer sell add clutter.
Decide which records your team needs to support current and near-term operations. Archive older records in a safe location for reference instead of loading them into Business Central.
A focused dataset improves performance and usability. Users work with current information, and reports reflect the reality of your business, not years of history that no one uses.
4. Map Your Fields
Field mapping shows how your current system matches the structure in Business Central. Review how each field in your legacy system lines up with fields in Business Central.
Note differences in names, formats, and types. Document this mapping so everyone understands how each value will transfer.
Good field mapping prevents failed imports and reduces data issues during testing. It also makes it easier to explain changes to users who will work with the new system.
5. Run Test Imports
Test imports reveal problems before they affect your go live. Use real data samples when you test. Import them into a Business Central sandbox and review the results.
Check that records appear in the right place, that values display correctly, and that required fields are filled. Run more than one test and refine your data and mapping each time.
These tests help you find and fix problems early. By the time you load your final dataset, you will know what to expect and can move more confidently into training and cutover.
6. Fix Inactive and Outdated Records
Over time, most systems collect inactive and outdated data. This includes old contacts, obsolete items, and vendors or customers that no longer work with you.
Identify these records and decide whether to remove or mark them inactive before migration.
Doing this work before you move to Business Central keeps your new environment clean. Users spend less time sorting through old records and more time working with information that matters.
7. Validate Financial Data
Financial data needs extra care. Review your chart of accounts, opening balances, tax fields, and account groupings. Confirm that these values tie to your current financial statements.
Make sure the accounts you will use in Business Central reflect your real structure.
Accurate financial data makes your first month end close in Business Central far easier. It also builds confidence with leadership and auditors, since they can see how the numbers match your previous system.
When you complete these steps, you create a structured and reliable dataset.
This becomes the base for stable processing and accurate reporting once Business Central is live.
