Many online stores reach internal limits during ongoing operations. Typical triggers include missing features, performance issues, rising maintenance costs, or an outdated system foundation that is no longer reliably developed. As a merchant, the question then becomes how to switch your ecommerce platform – including your entire data set and ongoing revenue – without disrupting your business.
Switching ecommerce platform: Key takeaways
Switching your ecommerce platform makes sense when your current system reaches its limits, becomes too expensive to operate, or lacks essential functionality.
The best time to switch is outside your peak periods, ideally with a six‑to‑eight‑week buffer.
Start by choosing the right system type (SaaS, PaaS, or self‑hosted).
Clearly define your requirements for features, integrations, internationalization, and marketing processes.
Fully test the new shop in a staging environment: products, checkout, payment methods, shipping, customer data, and integrations.
Downtime can be minimized by fully preparing the new shop and switching during a short cutover window.
Shopware supports migrations with a dedicated Migration Assistant, documented migration paths, and a strong partner network.
Pre-checklist: Should I switch my ecommerce platform?
My shop is slow or occasionally unstable, especially under high traffic.
Updates regularly cause issues or are avoided due to risk concerns.
Important features (for example, B2B or internationalization) are missing or difficult to implement.
New requirements can only be implemented with significant effort.
Maintenance and agency costs are increasing without added value.
Planned growth or digitalization goals cannot be realized in the current system.
Additional indicators that switching is the right decision include outdated and sluggish software, unreliable integrations with ERP, PIM, or CRM systems, and the overall desire for a future-proof ecommerce platform.
Guide: Switching your ecommerce platform
Your platform migration succeeds when you first select the new system, define your requirements, document your current state, determine the migration strategy, and thoroughly test the new shop before going live.
Step 1: Choose the right system type
Your choice of system type determines future flexibility, maintenance effort, and available features.
System type | Description | Advantages | Disadvantages |
|---|---|---|---|
SaaS (Software-as-a-Service) e.g. Shopware SaaS | Fully managed cloud operation. Updates, security, and infrastructure are handled by the provider. | Very low maintenance effort; fast implementation; stable and scalable; no server administration costs | Limited deep customization; dependent on provider’s feature scope |
PaaS / Cloud-native e.g. Shopware PaaS | Cloud hosting with greater control over architecture and custom code. | Broad flexibility; API-first; headless options; ideal for complex integrations and highly individual requirements | Requires technical expertise or agency support; higher development/DevOps costs |
Self-hosted / Open source | Operated on your own infrastructure or with a hosting partner. | Maximum customization; full control over code and server; independent of SaaS limitations; popular for complex B2B setups | Higher operational and maintenance effort; updates and security are your responsibility |
Step 2: Assess your current state
Document your existing shop environment to understand what needs to be migrated.
Area | What to document | Why it matters |
Products | Quantity, variants, images, attributes | Foundation for data migration |
Customer data | Accounts, groups, opt-ins | Controls pricing, permissions, GDPR compliance |
Orders | Time period and volume of order history | Essential for customer service and reporting |
Content | Pages, landing pages, media | Important for SEO, marketing, and navigation |
Integrations | ERP, PIM, CRM, payment, shipping | Ensures business processes continue to function |
Custom features | Pricing logic, exports, automations | Identifies individual customization needs |
Step 3: Define your requirements (target state)
To ensure a successful migration, clearly outline your business and technical requirements.
Business models: The new system must support your real sales scenarios, such as B2C with variant logic, B2B with customer-specific pricing and approval workflows, or D2C with recurring orders.
Planned growth: If you plan to expand into additional countries, languages, or currencies, you need multilingual capabilities, country-specific tax and shipping rules, and scalable pricing and catalog logic.
Marketing and content requirements: If your team frequently publishes campaigns, landing pages, or product stories, the system should include a CMS usable without developers, support multiple media formats (images, videos, 3D), allow layout adjustments without code changes, and provide reusable modules and templates.
Stable integrations with ERP, PIM, CRM, POS, or marketplaces.
Reliable performance and scalability during peak traffic.
Step 4: Define your migration strategy
Determine how the migration will technically proceed, which data will be transferred, and how operations remain uninterrupted.
Option 1: One-step migration
The shop is completely rebuilt and then populated with all relevant data in a single import.
Suitable when:
The existing shop is small or outdated.
Few custom functions must be migrated.
A short transition phase is acceptable.
Advantage: Fast completion
Disadvantage: Less testing time
Option 2: Migration with staging and multiple data imports
The new shop runs as a staging version. Data is imported multiple times for testing and adjustments.
Suitable when:
Many integrations exist.
Custom functionality must be considered.
SEO, tracking, or B2B processes require careful transfer.
Advantage: Lower risk
Disadvantage: Longer project timeline
Option 3: Parallel operation with delta migration
An initial full import is completed. Shortly before go-live, a second import (“delta”) updates new orders, customers, and changes.
Suitable when:
The shop must remain accessible throughout migration.
Large data volumes exist.
Daily orders or B2B quotes cannot be lost.
Advantage: Very secure transition
Disadvantage: Higher technical complexity
Step 5: Testing before go-live
Before launching, thoroughly test all relevant functions in a secure staging environment.
Requirements for testing
Independent staging environment
Realistic data set including products, customers, and orders
Access to all integrated systems (ERP, PIM, CRM, payment, shipping)
What to test
Products: Correct display? Variants, pricing, availability, tier pricing working?
Checkout: Seamless process? All payment methods functional? Shipping methods, delivery times, and costs accurate?
Customer data: Can existing customers log in? Registration and password reset working?
Integrations: Are orders correctly transferred to ERP? Is inventory synced? Do newsletter, tracking, and feed exports function?
Content: Are homepage, categories, and landing pages complete? Media and internal links working?
Team approval
Departments (customer service, marketing, logistics) review their areas.
Issues are collected and prioritized.
All open items are resolved before go-live.
Step 6: Protect SEO rankings and secure data
Prevent ranking and data losses by correctly redirecting existing URLs and ensuring complete data migration.
Set up 301 redirects for every old URL.
Transfer titles, descriptions, media, structured data, and internal links.
Update Google Search Console: submit new XML sitemap, check for crawl errors.
Test performance and Core Web Vitals via Google PageSpeed Insights.
Data security:
Before migration: Back up all products, customers, orders, and media.
After migration: Conduct spot checks to verify data accuracy.

When is the right time to switch ecommerce platforms?
The right time is when your current system reaches technical limits, maintenance effort increases, or goals such as internationalization, B2B functionality, or new sales channels can no longer be implemented.
Plan your migration outside high-revenue periods.
Suitable timing includes:
Quiet business phases outside seasonal peaks or campaigns.
Sufficient internal capacity for testing and validation.
Planned relaunch or expansion projects aligned with the new system.
Immediate action is required when:
Manufacturer support has ended.
Security or stability issues occur.
Integrations or updates are repeatedly delayed or failing.
Business goals cannot be implemented.
Switching ecommerce platform – frequently asked questions
Does my current shop need to go offline during migration?
No. The new shop is built in parallel. The actual switchover typically takes only a few minutes if data and systems are prepared.
Which data can be migrated?
Typically, products, variants, categories, customer accounts, orders, media, and many CMS contents can be migrated. The scope depends on the source system. In most migrations to Shopware, nearly the entire shop can be transferred.
Will I lose my Google rankings?
Not if all relevant URLs are redirected with 301 redirects and content is fully transferred.
How much does switching ecommerce platforms cost?
Costs vary widely. Small shops often range between €5,000–€20,000. Mid-sized shops typically range between €20,000–€80,000. Complex setups (B2B, ERP integrations) can exceed €100,000.
Do I need an agency for migration?
Not necessarily. Smaller shops may handle migration independently. Larger projects or those with many integrations benefit from Shopware partner support to avoid delays and errors.
When should I not migrate?
Avoid switching during peak periods such as Black Friday, holiday seasons, or major assortment or process changes. Choose stable and quiet business periods instead.
