Store migration is a process where the security of historical data plays a key role. Moving the customer database, order history, and active discount codes from Shoper to Shopify requires a precise technical approach to preserve operational continuity and customer relationships. A correctly executed transfer not only maintains sales analytics but above all enables a smooth transition for users to the new shopping environment without losing their privileges or interaction history with the brand.

Why customer and order data is the most valuable asset during migration

Data accumulated in an e-commerce system is the foundation of retention strategy and marketing personalization. Purchase history enables precise calculation of metrics such as Customer Lifetime Value (LTV) and Average Order Value (AOV)-essential for fact-based business decisions. Losing this information during a platform change means rebuilding the database from scratch, drastically increasing customer acquisition cost (CAC). A comprehensive Shoper to Shopify migration puts database security first, ensuring every record is correctly mapped and transferred to the new infrastructure. Data continuity is also a matter of trust-customers expect their accounts, shipping addresses, and transaction history to remain available regardless of the technology powering the store. Proper transfer enables user segmentation from day one after launch, supporting effective win-back campaigns or loyalty programs.

Exporting data from Shoper: Preparing the database for transfer

The first technical step is generating complete export files from the Shoper admin panel. The platform supports CSV export, but the process requires attention due to record limits and specific character encoding. Ensure files are saved in UTF-8 format to prevent errors displaying diacritics in names, surnames, or street names. Before importing customers, the full Shoper to Shopify migration is usually analyzed step by step to maintain the correct action sequence and avoid inconsistencies between the customer database and product catalog. For very large databases exceeding tens of thousands of records, splitting files into smaller batches is recommended to avoid exceeding server script execution time limits when generating reports.

Key export parameters

Select an export profile containing all required address fields (street, house number, postal code, city, country).
Split large data sets into smaller batches (e.g. 5,000 records each) to ensure transfer stability.
Verify email addresses, which serve as the unique account identifier in Shopify and must not duplicate.
Export additional fields such as customer notes or account creation dates, useful for later tagging.

Customer import into Shopify involves matching source file columns to the standard required by the new platform. Shopify uses a specific CSV schema where key fields include: Email, First Name, Last Name, Phone (international E.164 format), Address1, City, Province Code, and Country Code (ISO 3166-1 alpha-2). An important aspect is transferring marketing consents. In Shopify, the "Accepts Marketing" field handles this-setting it to "yes" for customers who consented in Shoper preserves the newsletter database in compliance with GDPR. Remember that failing to map this field imports all customers without consent, preventing email marketing campaigns immediately after migration.

Using tags to recreate customer groups

In Shoper, segmentation often relies on customer groups (e.g. VIP, Wholesale, Regular Customers). Shopify's base version does not have an identical groups module, so tags are used to recreate this structure. During import, each record can receive an appropriate tag for later automatic segment creation in the admin panel. These tags are also recognized by marketing automation apps, enabling specific pricing permissions or message personalization for selected groups without manual database filtering.

The password challenge: Why they do not transfer and how to activate accounts

A common migration phenomenon is that customer passwords cannot be transferred directly. This results from both platforms' high security standards-passwords are encrypted using one-way hashing algorithms, making them unreadable and unre-encryptable in another system. The solution is the Customer Account Activation process. After importing the database into Shopify, accounts have "Disabled" status. Send customers a system invitation containing a unique link to set a new password. A good practice is preparing an email explaining the technology change, reducing the risk of account abandonment. This process can be automated using built-in Shopify tools or external email marketing apps that allow invitation content personalization.

Communication strategy for account activation

Prepare a clear message about moving to a newer, more secure platform.
Explain the need to set a new password for personal data security.
Use the activation moment to offer a one-time bonus (e.g. a discount code) for completing the process.
Monitor account activation rates and send reminders to users who did not click the link on the first attempt.

Order history transfer: Methods and preserving relationships

Moving order history is more complex than importing the customer database alone, as it requires preserving relationships between the buyer, purchased product, and payment. Shopify's standard CSV importer has limited capabilities for archived orders, so larger databases use advanced tools such as Matrixify or direct Shopify API use. Order history continuity is essential for correct analytics, enabling reporting on metrics such as repeat purchase frequency or total order value per customer. In parallel with the order database, correctly moving products and categories ensures historical line items are correctly identified by the system and linked to the current assortment.

Order status mapping: Shoper vs. Shopify

During transfer, fulfillment statuses must be technically aligned. For example, an order marked "shipped" in Shoper should import into Shopify with "fulfilled" status. Disable automatic customer email notifications during import. Otherwise, Shopify might send mistaken fulfillment messages for orders from months or years ago, creating unnecessary communication chaos.

Discount codes and coupons: Migrating marketing campaigns

Active discount campaigns, one-time codes, or newsletter subscriber coupons must be recreated in the Shopify admin so customers do not lose benefits after migration. Shopify supports bulk discount code import via CSV files or dedicated apps. When preparing the file, precisely define each discount's parameters: fixed amount, percentage, or free shipping. Transfer usage limits (e.g. single-use codes), minimum cart value required to activate the discount, and expiration dates. For codes automatically generated by loyalty apps in Shoper, you may need to export their database and manually import into an equivalent Shopify solution. Correctly recreating these rules ensures promotional actions planned on the old platform finish without disruption.

Verification and testing: How to check data accuracy

After import, rigorous quality control (QA) is essential. Data errors can cause login problems, incorrect discount calculation, or gaps in financial reports. Base the verification checklist on the following points:

Compare total customer record counts in Shoper and Shopify to detect omissions.
Spot-check customer profiles for address, phone number, and segmentation tag accuracy.
Verify total historical order values for selected customers in both systems.
Test migrated discount codes in the cart on the new platform to validate rules.
Confirm Customer Activation works and email links lead to the correct pages in the new store.
Verify marketing consent is correctly assigned to customer profiles.

Technical summary of data transfer

Moving data from Shoper to Shopify requires meticulous work at every stage-from export through field mapping to end-customer communication. Success depends on understanding structural differences between both platforms and using appropriate tools for order history transfer. Historical data transfer is part of an e-commerce implementation focused on scaling sales and profitability. Preserving information continuity enables continued sales activities using the new platform's analytics while maintaining customer relationships.

FAQ

Can customer passwords be migrated from Shoper to Shopify?

Direct password transfer is not possible due to different encryption algorithms on both platforms. After migration, send customers a system account activation invitation to set a new password.

How do you import order history into Shopify?

Order history can be moved via CSV files (with limitations), dedicated apps such as Matrixify, or solutions using the Shopify API to preserve full product and customer relationships.

Will Shoper discount codes work in Shopify?

Discount codes must be recreated in the Shopify admin-manually or via CSV import-defining parameters such as discount value, minimum order amount, limits, and expiration dates.

How do you avoid duplicate customer accounts during migration?

Use the unique identifier, which in Shopify is the email address. Before import, clean the Shoper database by removing duplicates and ensuring each customer has one valid email.

Will customers keep loyalty points after migration?

Loyalty points do not transfer automatically. Export point balances from Shoper and import them into a chosen Shopify loyalty app using customer tags or dedicated import tools.

Marketing consents transfer by mapping the "Accepts Marketing" field in the CSV. A "yes" value automatically subscribes the customer in Shopify, preserving email marketing continuity.
