Salesforce Data Migration: What Is It & How to Set It Up?

Data migration is a critical aspect of any Salesforce implementation or upgrade. Whether you’re moving data from a legacy system, consolidating databases, or transitioning to Salesforce from another CRM platform, the data migration process is pivotal to the success of the transition. Poorly executed migrations can lead to data loss, corruption, and operational disruptions.
In this comprehensive guide, we’ll explore the fundamentals of Salesforce data migration, offer expert advice from Synebo’s seasoned consultants, and provide actionable steps to ensure a smooth, error-free migration. You’ll learn the best practices, the technical requirements, and the tools that can help you migrate your data securely and efficiently.
What Is Salesforce Data Migration?
Salesforce data migration is the process of transferring your organization’s data from one system to Salesforce. This involves not only moving the data but also ensuring it is correctly formatted, mapped, and stored in Salesforce’s architecture. The migration process typically includes customer records, transactional data, historical data, and more, depending on your business needs.
Why Salesforce Data Migration Matters
Data is the backbone of any organization. Migrating it to Salesforce allows businesses to leverage the platform’s full CRM potential while maintaining historical accuracy. A successful migration ensures:
- Data integrity: Accurate, clean data that can be effectively used across the platform.
- Improved decision-making: Access to comprehensive customer data helps inform strategic business decisions.
- Operational efficiency: With all data in one place, Salesforce enables seamless collaboration and automation.
“Data migration is not just a technical task—it’s a strategic move that impacts every part of your business. Done right, it sets the foundation for future success.” — Chief Data Architect, Synebo
How to Set Up Salesforce Data Migration: A Step-by-Step Guide

1. Plan Your Migration Strategy
A well-thought-out migration strategy is essential to avoid data loss and operational disruptions. At Synebo, we recommend conducting a thorough audit of your data before migration. This involves identifying:
- Data sources: Know where your data is currently stored (e.g., legacy systems, spreadsheets, databases).
- Data format: Ensure that the data is in a format compatible with Salesforce.
- Critical data: Identify which data is crucial for migration and which can be archived or discarded.
“The first step in any migration project is creating a clear roadmap. Identify what needs to be migrated, why it’s important, and what data can be cleaned or left behind. This saves time and ensures data quality.” — Head of Data Migration, Synebo
2. Data Mapping
Data mapping is crucial for ensuring that the information in your old system corresponds correctly to Salesforce. Misaligned data fields can lead to errors, so it’s essential to have a clear mapping structure.
Key Data Mapping Considerations:
Data Type |
Source Field (Legacy System) |
Destination Field (Salesforce) |
Special Notes |
Customer Name |
Customer_Name |
Account.Name |
Ensure no abbreviations are used |
Order History |
Order_History |
Opportunity.StageHistory |
Map order stages to Salesforce stages |
Contact Details |
Contact_Details |
Contact.Email |
Validate email formats during migration |
Synebo’s team leverages automated mapping tools like MuleSoft or native Salesforce tools like Data Loader and Apex Data Loader to ensure seamless data transitions.
3. Data Cleansing
Data cleansing is a vital step in ensuring the integrity of your Salesforce environment. Migrating poor-quality data can lead to inefficiencies, duplicate records, and inaccurate reporting. At Synebo, we recommend:
- Deduplication: Use tools like Salesforce’s native Duplicate Management or third-party applications like Cloudingo to identify and remove duplicates.
- Data validation: Ensure data formats are standardized (e.g., phone numbers, email addresses).
- Completeness checks: Make sure all necessary data fields are filled before migration.
“Data cleansing is an opportunity to refresh and optimize your data. Don’t carry over bad habits from your old systems—clean up your data and start fresh.” — Data Quality Specialist, Synebo

Common Data Migration Challenges and Solutions
1. Data Loss During Migration
Data loss is one of the biggest risks when migrating systems. This can occur due to incomplete data mapping or incorrect field formats.
Solution:
- Backup your data: Always back up your data before beginning the migration.
- Validation checks: Use validation rules during the testing phase to ensure all critical fields are populated.
“We never start a migration without a full backup in place. It’s your insurance policy in case anything goes wrong.” — Senior Migration Consultant, Synebo
2. Performance Issues During Large Data Migrations
Migrating large volumes of data can cause system performance issues, particularly if the migration is not optimized.
Solution:
- Batch migration: Break up large data migrations into smaller batches to avoid overwhelming the system.
- Utilize API limits: Be mindful of Salesforce’s API limits, especially if migrating through custom-built integrations.

Synebo Case Study: Financial Services Data Migration
Synebo recently assisted a financial services firm in migrating over 500,000 customer records from an outdated, on-premise CRM system to Salesforce. Due to the nature of the financial industry, the project required a high level of precision, strict adherence to regulatory standards, and sophisticated data transformation processes to ensure the seamless transfer of data.
The primary challenges faced during the migration were:
- Complex data structure: The legacy system contained various custom fields and historical financial data, much of which required careful restructuring to fit into Salesforce’s CRM architecture.
- Regulatory compliance: As a financial services provider, the firm needed to ensure that the migration complied with data protection laws like GDPR, requiring extra diligence in data handling and security.
- Data quality issues: The legacy system contained thousands of duplicate records, inconsistent formats, and outdated information, which needed to be cleansed before migration.
Synebo’s approach:
- Step 1: Detailed data audit and mapping
Synebo began by conducting a comprehensive audit of the data, identifying areas that required transformation. Custom mapping scripts were developed to ensure that all fields from the legacy CRM aligned with the correct fields in Salesforce. Special attention was given to financial data, which required secure and accurate transformation. - Step 2: Leveraging MuleSoft for real-time integration
Given the complexity of the data, Synebo employed MuleSoft for real-time synchronization between the old CRM and Salesforce. This allowed the team to perform incremental migrations, ensuring that the financial data remained accessible to the firm throughout the process.
“MuleSoft’s API-led approach allowed us to perform real-time data validation during the migration, ensuring accuracy without sacrificing operational continuity.” — Senior Integration Engineer, Synebo
- Step 3: Data cleansing and deduplication
Synebo used Cloudingo and MuleSoft’s built-in tools to cleanse the data, removing over 50,000 duplicate records. Data validation rules were applied to ensure that only clean, accurate data was migrated to Salesforce, significantly improving the firm’s data quality.

Synebo implemented robust encryption protocols during data migration, ensuring that all sensitive information was protected. A dedicated compliance team audited every step of the migration to verify that data handling met legal standards.
“Compliance isn’t optional in financial services. Our meticulous process ensured full GDPR compliance throughout the migration without slowing down the project.” — Compliance Officer, Synebo
- Step 5: Post-migration optimization
After the data migration was complete, Synebo worked with the client to optimize their Salesforce setup, creating automated workflows and custom dashboards to track financial data, customer transactions, and sales pipelines in real-time.
Key success factors:
