Oracle ATG Web Commerce to PrestaShop Migration - Step-by-Step Guide & Expert Services

Seamlessly Migrate Your E-commerce Store from Oracle ATG Web Commerce to PrestaShop

Replatforming your e-commerce store is a strategic decision that can significantly impact your business's future. While Oracle ATG Web Commerce offers enterprise-grade power, many merchants seek the agility, cost-effectiveness, and extensive community support of platforms like PrestaShop. This guide provides a detailed, step-by-step approach to seamlessly transition your valuable store data from Oracle ATG to PrestaShop, ensuring data integrity and a smooth replatforming process.

Given that Oracle ATG Web Commerce does not typically offer direct API or database access for standard migration tools, this guide will leverage a robust CSV file export from your Oracle ATG store, followed by an automated import into PrestaShop. This method ensures that all your critical e-commerce entities, from product SKUs and customer profiles to order histories and reviews, are transferred efficiently.

Prerequisites for a Successful Migration

Before embarking on your data transfer, ensuring both your source (Oracle ATG) and target (PrestaShop) environments are adequately prepared is crucial. Proper preparation minimizes downtime and potential issues during the migration.

For Your Oracle ATG Web Commerce Store (Source)

• Full Data Export: You will need administrative access to your Oracle ATG Web Commerce system to export all essential data entities (products, categories, customers, orders, manufacturers, reviews, CMS pages, blogs, coupons, etc.) into well-structured CSV files. Each entity should ideally have its own dedicated CSV file for clarity and ease of mapping.
• Data Cleansing: Prior to export, it is highly recommended to perform a thorough data cleanse. Remove duplicate entries, outdated product information, or inactive customer accounts to ensure only high-quality data is migrated to your new PrestaShop store.
• Comprehensive Backup: Always perform a complete backup of your Oracle ATG Web Commerce store and its database before initiating any data export process. This is a critical safety measure.
• Access Credentials: Ensure you have the necessary credentials and permissions within Oracle ATG to perform mass data exports.

For Your PrestaShop Store (Target)

• Fresh PrestaShop Installation: Have a clean, newly installed PrestaShop store ready. While you can migrate to an existing store, a fresh installation is often recommended to avoid conflicts and simplify the post-migration setup.
• Admin Access: You will need full administrator access to your PrestaShop backend. This includes the Admin URL, username, and password. For connecting the migration tool, you may also need FTP/SFTP access to the store's root directory. For more details on preparing your target store, read our guide on How to prepare Target store for migration?
• Hosting Compatibility: Confirm your hosting environment meets PrestaShop's system requirements to ensure optimal performance of your new store.
• Required Plugin: The migration process for PrestaShop typically requires the Cart2Cart Universal PrestaShop Migration module. Be prepared to install this plugin in your PrestaShop store.

Performing the Migration: A Step-by-Step Guide

This guide will walk you through using an automated migration wizard, which streamlines the process of moving your data from exported CSV files to PrestaShop.

Step 1: Initiate Your Migration

Begin by accessing the migration wizard. You'll typically be presented with options to start a do-it-yourself migration or request an assisted service. For this guide, we'll proceed with the DIY approach.

Step 2: Set Up Your Source Store (Oracle ATG via CSV)

Since Oracle ATG Web Commerce is not directly integrated with standard migration connectors, your data will be sourced from CSV files. Select 'CSV File to Cart' as your source platform in the migration wizard.

• Select CSV as Source: From the dropdown menu, choose 'CSV File to Cart'.
• Upload CSV Files: You will then be prompted to upload the CSV files containing your Oracle ATG data. Ensure your files are correctly formatted, with clear headers for each data field (e.g., product name, SKU, price, customer email, order ID). The system will guide you on the expected format. For a deeper dive, refer to our CSV.File Data Migration service.

Step 3: Connect Your Target Store (PrestaShop)

Now, it's time to connect your new PrestaShop store, which will serve as the destination for your transferred data.

• Select PrestaShop: Choose 'PrestaShop' from the list of target carts.
• Enter Admin URL: Provide the Admin URL of your PrestaShop store.
• Choose Connection Method: For PrestaShop, the most reliable connection method often involves uploading a Connection Bridge. You will typically:

1. Download a small bridge file from the migration service.
2. Extract the 'bridge2cart' folder from the downloaded zip file.
3. Upload this 'bridge2cart' folder to the root directory of your PrestaShop installation via FTP/SFTP. This is crucial for establishing a secure link for data transfer. If you're unsure about the root folder, check our What is a root folder and where can I find it? guide.
4. Alternatively, some tools offer an option to automatically install the required plugin (Cart2Cart Universal PrestaShop Migration module) by providing your PrestaShop admin credentials.

Step 4: Select Data Entities for Transfer

In this step, you will specify which data entities you wish to migrate from your CSV files to PrestaShop. The migration tool typically supports a wide range of data, including:

• Products (SKUs, variants, descriptions, images)
• Product Categories
• Product Manufacturers
• Product Reviews
• Customers (with password migration options)
• Orders (historical data, statuses)
• Invoices
• Taxes
• Store information
• Coupons
• CMS Pages
• Blogs & Blog Posts

You can choose to migrate 'All entities' with a single click or selectively pick specific data types based on your business needs.

Step 5: Configure Additional Migration Options

This stage allows you to customize your migration with various advanced options to fine-tune the data transfer and preserve critical information:

• Preserve IDs: Options like 'Preserve Product IDs', 'Preserve Category IDs', 'Preserve Orders IDs', and 'Preserve Customers IDs' are vital for maintaining internal references and preventing broken links. Learn more about How Preserve IDs options can be used?
• Migrate Images in Description: Ensure product images embedded within descriptions are transferred correctly.
• Password Migration: Migrate customer passwords to ensure a smooth transition for your existing customer base.
• Create 301 SEO URLs: Crucial for maintaining your search engine rankings and link equity. This option creates redirects from your old Oracle ATG URLs to the new PrestaShop URLs.
• Clear Target: If you are migrating to an existing PrestaShop store and wish to remove all current data before importing new data, select 'Clear Target'. For more information, read about the Clear current data on Target store before migration option.
• Create Variants from Attributes: Essential if your products have variations (e.g., size, color) defined by attributes in your Oracle ATG data.
• Multi-tax Allowed: Supports complex tax structures if your business operates in multiple regions.
• Skip Custom Attributes: Allows you to exclude custom product or customer attributes from migration if they are not needed in PrestaShop.

Step 6: Map Data Fields

Accurate data mapping is essential for ensuring that information from your Oracle ATG CSV files aligns correctly with PrestaShop's data structure. This step usually involves matching:

• Customer Groups Mapping: Align customer roles (e.g., 'Wholesale', 'Retail') from your source data to corresponding groups in PrestaShop.
• Order Statuses Mapping: Match order states (e.g., 'Pending', 'Processing', 'Shipped') from your CSVs to PrestaShop's order statuses.

The wizard will provide intuitive dropdowns to facilitate this process, ensuring data consistency and integrity.

Step 7: Run a Free Demo Migration (Optional but Recommended)

Before committing to a full migration, it's highly recommended to perform a free demo. This allows you to migrate a limited number of entities (e.g., 10-20 products, customers, and orders) to your PrestaShop store. The demo helps you:

• Verify the accuracy of the data transfer.
• Check if all mappings are correct.
• Identify any potential issues before the full migration.

This is a valuable Migration Preview Service that can save significant time and effort.

Step 8: Perform the Full Data Migration

Once you're satisfied with the demo results, proceed with the full data migration. Review the summary of your selected entities and the estimated cost. You may also consider adding Migration Insurance Service, which offers additional remigrations within a specified period, providing extra peace of mind.

Post-Migration Steps

Completing the data transfer is a significant milestone, but the process doesn't end there. Several crucial post-migration steps are necessary to ensure your new PrestaShop store is fully operational and optimized.

• Verify Data Integrity: Conduct a thorough audit of your PrestaShop store. Check product details (SKUs, variants, prices, images), customer accounts, order histories, reviews, and CMS pages to ensure everything has transferred accurately.
• Configure Store Settings: Set up essential store configurations in PrestaShop, including payment gateways, shipping methods, tax rules, store locations, and currency settings.
• Install and Customize Theme & Modules: Choose and install your desired PrestaShop theme. Install any necessary modules or plugins that replicate the functionality of your old Oracle ATG store or add new capabilities.
• Test All Functionality: Rigorously test every aspect of your new store: place test orders, register new customer accounts, verify the search function, ensure all links work, and confirm the checkout process is smooth.
• Set Up 301 Redirects: Even if the migration tool created 301 redirects, double-check them. If you have custom URLs or specific SEO requirements, ensure all critical old URLs redirect to their new counterparts to preserve your SEO rankings and link equity.
• Update DNS and Go Live: Once satisfied with the setup and testing, update your domain's DNS records to point to your new PrestaShop store. Announce the transition to your customers!
• Monitor Performance: Keep a close eye on your new store's performance, site speed, user experience, and SEO metrics. Address any issues promptly.

Migrating from Oracle ATG Web Commerce to PrestaShop, while involving a CSV-based approach, can be a smooth and efficient process with the right tools and preparation.
