Salesforce data migration involves transferring data from your current CRM software and other corporate systems to Salesforce or between different Salesforce orgs. This process is essential for consolidating customer data, improving data accessibility, and streamlining cross-departmental operations.

As a Salesforce Partner since 2019, Itransition provides Salesforce consulting services to help companies streamline the migration process through careful planning, accurate data preparation, and post-migration validation.

Salesforce data migration steps

A typical Salesforce migration project involves multiple phases that begin well before the actual data transfer.

1

Planning

Start by aligning with key stakeholders to define the project’s goals, scope, and timelines. Then, form the Salesforce data migration team, select the toolkit, and establish a migration strategy. Make sure your strategy includes risk mitigation measures (e.g. data backups, migration monitoring, and error logging), change management practices (e.g. communicating changes in user workflows to stakeholders), and user onboarding initiatives (e.g. employee training). In addition, create a Salesforce data migration checklist to make sure that no critical migration activities are overlooked.

2

Data selection

Next, determine what sales, marketing, and customer data and metadata to migrate to Salesforce in line with the project’s goals and the new system’s setup. You should also identify sources for migration (legacy CRM, databases, other business apps, another Salesforce org, etc.), the data model structure (how data will be organized in objects and fields), and data types (accounts, contacts, etc.) in the target system. It is often better to archive outdated or unused data and only migrate high-quality, relevant records to the new system.

3

Data mapping & extraction

Match data fields in the source system (contacts, leads, etc.) to the corresponding fields in the Salesforce objects of the target system. This will help you ensure seamless data transfer and reduce the risk of data corruption or other potential errors. Then, pull out data from the source system via data extraction tools.

4

Invalid data detection

Since legacy systems often allow the entry of invalid data and Salesforce enforces data quality at the bare minimum in data types (dates, IDs from other tables, etc.), you need to identify invalid source data early on to prevent it from causing errors during the migration.

5

Data transformation & cleaning

Transform source data into a format compatible with Salesforce data structures and perform thorough data cleaning to delete duplicates or outdated information.

6

Destination org preparation

Prepare the target Salesforce org for data migration by setting up the necessary objects and fields. This includes creating custom fields and relationships for data that should be stored in non-standard fields.

7

Data loading

Load the extracted and transformed data to the new Salesforce environment using suitable data migration tools based on data volume and complexity.

8

Data validation

Apply validation rules to check the integrity and accuracy of the migrated data (e.g. its format and completeness) and fix detected errors. At this stage, perform user acceptance testing (UAT) to make sure stakeholders are satisfied with the results of the Salesforce data migration.

Salesforce data migration best practices

Select the data carefully

Dedicate some time to sorting out your datasets and weighing up what definitely needs to be migrated and what doesn’t. By approaching data selection prudently, companies can reduce the project’s timeline and prevent potential data migration conflicts.

Back up the data

Always create a complete copy of the source data before beginning the migration. If corruption occurs during mapping or loading, you can restore your business-critical information without permanent data loss.

Test migration with a dry run

Before migrating data to the production environment, perform a test run in a sandbox and verify the results to make sure that everything works as expected. Plan this operation carefully to make it easily reproducible, since you’re supposed to repeat the process at least once during the production migration or multiple times if something goes wrong.

Establish a data governance & security strategy

Managing data properly when switching to a new platform can be difficult, so a data governance strategy can simplify keeping track of data quality, reliability, and integrity before, during, and after the migration. At the same time, you also need to implement data security practices to avoid leaks as you migrate data and ensure compliance with relevant regulations (such as GDPR or HIPAA).

Create data templates

Create data mapping documentation with the required fields and in a format (such as templates and spreadsheets) that is easy for the customer to understand, and populate it with the objects to migrate. You can also reuse such templates in the future and simplify further data migrations.

Start with a pilot project

If Salesforce is a completely new CRM system for your company, the differences between its and your legacy system’s data structure can cause conflict during migration. We recommend migrating a small amount of data to a sandbox environment and monitoring the process in real-time to gauge the potential challenges.

Data management trends

While data integration and migration to Salesforce can pave the way for more informed decision-making and increased business profitability, only adopters with robust data management strategies and practices fully realize these benefits.

53% of Salesforce customers name poor data availability and quality as the top barrier for adopting agentic AI.

IBM

84% of data and analytics leaders say their data strategies need significant changes to make their AI initiatives succeed.

Salesforce

Nearly all (97%) Salesforce users surveyed rely on expert technology partners to support their implementation initiatives in areas such as data integration.

IBM

44% percent of Salesforce teams surveyed said they back up their production org daily, while 18% do so weekly.

Gearset

90% of contacts stored in the average Salesforce customer's database are incomplete, and 20% of the records are useless (e.g., obsolete or duplicate records). This poor data quality costs companies an estimated $700 billion annually, or 30% of the average company’s revenue, and should be addressed via accurate data cleansing and validation.

Benefits of data migration to Salesforce CRM

Performing Salesforce data migration the right way

Performing Salesforce data migration the right way

The value and ROI of Salesforce depend on the quality of data it handles, which makes data migration a critical step in Salesforce implementation. A properly planned and executed data migration ensures that your Salesforce solution leverages high-quality data, driving business growth instead of being a repository for bad data.

That said, a successful migration requires the right tools, practices, and expertise. As for the latter point, Itransition’s experts are ready to help you ensure a seamless transition from your legacy CRM to a more powerful Salesforce solution.
