TABLE OF CONTENT
If you are running an online store on Shopware 5, you have probably heard the news — Shopware 5 reached its official end of life, meaning it no longer receives security updates or feature improvements from the Shopware team. That alone is a strong enough reason to think seriously about migrating to Shopware 6. But beyond security, Shopware 6 is a fundamentally better platform — faster, more flexible, more modern, and built for the future of e-commerce.
The good news is that migration is very much doable — even for large stores with thousands of products and a complex setup. In this guide, we will walk you through every step of the process in plain language, so you know exactly what to expect, what to prepare, and how to avoid the most common mistakes that trip people up.
⚠ Important Before You Start
Always work on a staging (test) environment first. Never perform migration steps directly on your live production store. Mistakes can cause data loss that is very difficult to reverse.
1. Why Choose 24Infotech?
Shopware 6 is not just an upgrade — it is a complete rewrite of the platform. Shopware built it from scratch using modern technologies like Symfony 5, Vue.js for the admin panel, and a powerful API-first architecture. Here is why this matters for your business:
- Security: Shopware 5 no longer gets security patches. Running it exposes your store and your customers’ data to serious risk.
- Performance: Shopware 6 is significantly faster out of the box, especially with its built-in Elasticsearch support and improved caching.
- Headless capability: Shopware 6 comes with a full Store API, so you can build your own custom frontend or connect to any modern frontend framework.
- Better admin experience: The new admin panel is built with Vue.js and is far more responsive and user-friendly than Shopware 5’s backend.
- Active ecosystem: All new plugins, apps, and integrations are being built for Shopware 6 — the Shopware 5 plugin ecosystem is essentially frozen.
2. Key Differences Between Shopware 5 and Shopware 6
Before diving into the migration steps, it helps to understand just how different these two platforms are. This is not like upgrading from WordPress 5 to WordPress 6 — it is more like switching from one platform to another that happens to have the same brand name.
| Feature | Shopware 5 | Shopware 6 |
|---|---|---|
| Framework | Zend Framework / Symfony 3 | Symfony 5+ |
| Frontend template engine | Smarty | Twig |
| Admin panel technology | ExtJS | Vue.js |
| Plugin system | Legacy plugin system | App System + Plugin System |
| API-first architecture | ✗ Limited REST API | ✓ Full Store API + Admin API |
| Headless commerce support | ✗ No | ✓ Yes, built-in |
| Security updates | ✗ End of Life | ✓ Active support |
| Theme format | LESS + Smarty | SCSS + Twig |
As you can see, almost every layer of the platform is different. This means your existing Shopware 5 plugins and themes will not work in Shopware 6 — they need to be rebuilt or replaced. The data itself (products, orders, customers) can be migrated, but the code cannot.

3. What to Prepare Before You Start Migrating
Rushing into a migration without preparation is the number one reason migrations fail or take far longer than expected. Here is what you need to do before you touch a single file:
1
Take a full backup of your Shopware 5 store
Back up all files and the complete database. Store this backup somewhere safe — ideally both locally and on cloud storage.
2
Audit your plugins
Make a list of every plugin you use in Shopware 5. Then check the Shopware store to see if a Shopware 6 version exists. Many popular plugins have been rebuilt for SW6.
3
Set up a fresh Shopware 6 installation
Install a clean Shopware 6 on a staging server. Do not try to upgrade in place — it does not work that way. SW6 needs a fresh installation.
4
Plan your new theme
Your Shopware 5 theme will not transfer. Decide whether to use a Shopware 6 ready-made theme from the store, or have a developer build a custom one.
5
Prepare your SEO data
Export all your existing URL slugs, meta titles, and meta descriptions. You will want to preserve these in Shopware 6 to avoid losing your Google rankings.
4. The Step-by-Step Migration Process
Shopware provides an official plugin called the Shopware Migration Assistant (available free in the Shopware store) that handles the heavy lifting of moving your data. Here is how the full process works:
Step 1 — Install the Migration Assistant on Shopware 6
Go to your Shopware 6 admin panel, open the Extension Manager, search for “Migration Assistant”, and install it. This plugin creates a bridge between your old SW5 database and the new SW6 installation.
Step 2 — Connect to your Shopware 5 database
Inside the Migration Assistant, you will enter your Shopware 5 database credentials — host, database name, username, and password. The plugin will read directly from your old database and map the data to the new format.
Step 3 — Run the data check
Before migrating, the assistant scans your SW5 data and tells you exactly what can and cannot be migrated automatically. Pay close attention to this report — it will flag things like custom fields, extensions, or data that needs special handling.
Step 4 — Migrate your data in order
Always migrate data in this specific order to avoid broken relationships between records. For example, if you migrate orders before customers, the orders will have no customer linked to them.
- System settings — languages, currencies, countries, tax rules
- Categories — your product tree and navigation structure
- Manufacturers / brands
- Products — including variants, prices, and images
- Customers — account data and addresses
- Orders — order history and status
- CMS pages — basic content pages (these need manual review after migration)
💡 Pro Tip: Media Files
Product images and other media are migrated separately. The Migration Assistant will download them from your SW5 server and re-upload them to SW6’s media manager. This can take a long time for large stores — plan accordingly and run it during off-peak hours.
Step 5 — Verify the migrated data
After migration completes, do not assume everything is perfect. Spot-check a random selection of products, check a sample of customer accounts, and verify that a few historical orders look correct. Check that all product variants, stock levels, and prices have come across properly.
5. Handling Plugins and Themes
This is the part of the migration that requires the most manual work. As mentioned earlier, no Shopware 5 plugin or theme works in Shopware 6. Here is how to approach each:
For plugins
Go through your audit list from the preparation phase. For each plugin, you have three options: find the official Shopware 6 version in the store and purchase it; find a comparable alternative plugin for SW6; or have a developer rebuild the plugin’s functionality as a native Shopware 6 plugin or App.
For themes
If you had a custom Shopware 5 theme, you will need to build a new one for Shopware 6. Shopware 6 uses Twig for templates and SCSS for styles — both are more modern and easier to work with than Smarty and LESS. A competent developer can typically rebuild a typical theme in one to three weeks, depending on complexity.
“The best time to rethink your storefront design is during a migration. Starting fresh with Shopware 6’s modern theme system often leads to better performance and a better customer experience than simply trying to replicate the old look.”
6. Testing Before Going Live
Never skip this phase. A thorough testing phase is what separates a smooth migration from a chaotic one. Here is a basic checklist of what to test on your staging environment:
- Can customers browse and search for products without errors?
- Do product variants (size, colour, etc.) display and select correctly?
- Can a customer add a product to the cart and complete a full checkout?
- Do all payment methods process correctly (test with sandbox credentials)?
- Are all shipping methods calculating correctly?
- Do customer login, account creation, and password reset work?
- Are automated emails (order confirmation, shipping, etc.) sending correctly?
- Do all URLs from your old store redirect to the correct new pages (301 redirects)?
- Does the store look and work properly on mobile devices?
- Do all your custom discount rules and promotions work correctly?
7. Common Mistakes to Avoid
After helping many businesses through this process, there are a handful of mistakes that come up again and again. Being aware of them in advance can save you a lot of time and frustration:
!
Forgetting 301 redirects
Your old Shopware 5 URLs look different from your new SW6 URLs. Without setting up 301 redirects, every Google-indexed page will show a 404 error, and you will lose your search rankings almost immediately.
!
Migrating directly on the live store
Always use a staging environment. Running migration on production risks breaking your live store for hours or even days if something goes wrong.
!
Ignoring custom fields
If you had custom product fields in SW5, the Migration Assistant may not carry all of them over perfectly. Always check custom field data manually after migration.
!
Not informing customers
If customers will be asked to reset their passwords (which sometimes happens due to password encryption differences), send them an email in advance so they are not confused when they cannot log in.
8. Conclusion — Is It Worth It?
Absolutely, yes. Migrating from Shopware 5 to Shopware 6 is not a small project, but it is a necessary one — and the long-term benefits far outweigh the short-term effort. You get a more secure platform, better performance, a modern admin interface, access to all new plugins and integrations, and a future-proof foundation for your business.
The key is to approach it with proper planning. Back up your data, test everything on staging, handle your plugins and themes proactively, and set up proper redirects before going live. If you follow the steps in this guide, your migration can be completed smoothly — with your products, orders, and customers all safely carried over to your new Shopware 6 store.
