The Migration Testing Bottleneck
Traditional Atlassian Cloud migration testing typically involves:
- Setting up complete test environments
- Synchronizing users, groups, and permissions
- Installing and configuring all plugins
- Migrating test data sets
- Waiting for indexing and processing
This process can easily consume entire days, making iterative testing and rapid validation cycles nearly impossible. For organizations facing the March 2026 deadline, this traditional approach simply isn't sustainable.
The SDK + ngrok Solution
The Atlassian SDK combined with ngrok offers a game-changing approach. Instead of full environment setup, you can:
- Run local Atlassian instances using the SDK
- Expose them securely to the web using ngrok
- Test specific migration scenarios without unnecessary overhead
- Iterate rapidly on configuration and customization
This approach lets you focus on what matters most: validating your specific use cases, plugins, and workflows without the overhead of complete environment replication.
Setting Up Your Lightning-Fast Test Environment
Prerequisites
Before diving in, ensure you have:
- Atlassian SDK installed
- ngrok account and CLI setup
- Java Development Kit (JDK) 8 or 11
Step 1: Configure Your Maven Project
Start with a clean Confluence SDK project and configure your pom.xml for HTTPS support:
...
<build>
<plugins>
<plugin>
<groupId>com.atlassian.maven.plugins</groupId>
<artifactId>confluence-maven-plugin</artifactId>
<version>${amps.version}</version>
<extensions>true</extensions>
<configuration>
<productVersion>${confluence.version}</productVersion>
<productDataVersion>${confluence.data.version}</productDataVersion>
<enableQuickReload>true</enableQuickReload>
<quickReloadVersion>2.0.0</quickReloadVersion>
<allowGoogleTracking>false</allowGoogleTracking>
<jvmArgs>
--add-opens java.base/sun.util.calendar=ALL-UNNAMED
-Xmx4g -Xms4g
</jvmArgs>
<contextPath>${tomcat.contextPath}</contextPath>
<!-- HTTPS Configuration (uncomment after setup) -->
<!--
<useHttps>true</useHttps>
<httpsPort>8777</httpsPort>
<httpsKeystoreFile>${project.basedir}/keystore.jks</httpsKeystoreFile>
<httpsKeystorePass>changeit</httpsKeystorePass>
<httpsKeyAlias>your-ngrok-domain.ngrok-free.app</httpsKeyAlias>
-->
...
</configuration>
</plugin>
...
</plugins>
</build>
...
Step 2: Initial Setup and ngrok Tunnel
Start your local instance without HTTPS first:
atlas-debug
Create your ngrok tunnel (in a separate terminal):
ngrok http https://localhost:8777
Copy your ngrok URL (something like https://a1b2c3d4e5f6.ngrok-free.app)
Step 3: SSL Certificate Generation
Generate a keystore with your ngrok domain:
nkeytool -genkey -keyalg RSA \
-alias a1b2c3d4e5f6.ngrok-free.app \
-keystore keystore.jks \
-storepass changeit \
-validity 360 \
-keysize 2048 \
-dname "CN=a1b2c3d4e5f6.ngrok-free.app, OU=Dev, O=Dev, L=City, ST=State, C=FI"
Step 4: Tomcat Proxy Configuration
Navigate to your Tomcat configuration and update the HTTP connector:
# Edit: target/container/tomcat9x/apache-tomcat-9.0.76/conf/server.xml
Update the connector configuration:
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443"
maxParameterCount="1000"
proxyName="a1b2c3d4e5f6.ngrok-free.app"
proxyPort="443" />
Step 5: Enable HTTPS and Restart
- Uncomment the HTTPS configuration in your
pom.xml - Update the ngrok domain in the configuration
- Restart atlas-debug
The system will automatically generate the HTTPS connector configuration:
<Connector SSLEnabled="true" URIEncoding="UTF-8" clientAuth="false"
connectionTimeout="20000" keyAlias="a1b2c3d4e5f6.ngrok-free.app"
keystoreFile="/path/to/keystore.jks" keystorePass="changeit"
maxParameterCount="1000" maxThreads="48" port="8777"
protocol="HTTP/1.1" proxyName="a1b2c3d4e5f6.ngrok-free.app"
proxyPort="443" redirectPort="8443" scheme="https"
secure="true" sslProtocol="TLS" />
Step 6: Access Your Public Instance
Your Atlassian instance is now accessible worldwide:
- Confluence:
https://a1b2c3d4e5f6.ngrok-free.app/confluence - Jira:
https://a1b2c3d4e5f6.ngrok-free.app/jira
Why This Approach Is Revolutionary for Migration Testing
1. Rapid Iteration Cycles
Instead of waiting hours for environment setup, you can spin up test scenarios in minutes. Test a plugin configuration, tear it down, and try a different approach – all within a single work session.
2. Focused Testing
No need to migrate entire user bases or complete data sets. Create minimal, targeted test scenarios that validate specific migration concerns without the overhead.
3. Remote Collaboration
Share your ngrok URL with stakeholders, allowing them to interact with your test instance in real-time. Perfect for getting immediate feedback on migration decisions.
4. Cloud Integration Testing
Test how your local customizations will behave when exposed to the internet, including webhook integrations, external app connections, and cloud-based services.
5. Cost-Effective Validation
Avoid spinning up expensive cloud instances for every test scenario. Use your local development machine's resources efficiently.
Real-World Migration Scenarios
Plugin Compatibility Testing
Quickly validate whether your critical plugins work correctly in different Confluence or Jira versions:
# Test with Confluence 7.19.x
atlas-debug -v 7.19.0
# Validate plugin behavior via ngrok URL
# Switch to Confluence 8.x
atlas-debug -v 8.5.0
Theme and Customization Validation
Test custom themes, templates, and UI modifications against the target cloud environment without full migration overhead.
Integration Testing
Validate webhook integrations, REST API calls, and third-party service connections using your publicly accessible ngrok URL.
User Experience Testing
Share your test instance with end users to gather feedback on proposed changes before committing to full migration.
Best Practices for SDK + ngrok Testing
1. Version Alignment
Always test against the exact Confluence/Jira versions available in Atlassian Cloud to avoid compatibility surprises.
2. Data Minimization
Use minimal data sets that represent your key use cases rather than full production data dumps.
3. Security Considerations
Remember that ngrok URLs are publicly accessible. Use test data only and avoid exposing sensitive information.
4. Configuration Documentation
Document your test configurations and results. The rapid iteration capability means you can easily lose track of what worked and what didn't.
5. Incremental Testing
Test one component at a time. The speed of this approach allows for granular validation of individual features.
Preparing for the March 2026 Deadline
With Confluence Cloud's legacy editor retirement approaching rapidly, this testing methodology becomes even more critical. You can:
- Test new editor compatibility with your existing macros and content
- Validate third-party app behavior with the new editor
- Assess user training needs by providing early access to the new interface
- Identify migration blockers before they become critical issues
The Competitive Advantage
Organizations using this SDK + ngrok approach for migration testing report:
- 90% reduction in testing cycle time
- Earlier identification of migration issues
- Improved stakeholder buy-in through interactive demos
- Reduced migration risk through thorough validation
Alternative Approach: Atlassian Docker Images
While this blog post focuses on the Atlassian SDK approach, it's worth noting that Atlassian Docker images offer another compelling path for migration testing that deserves consideration for future exploration.
Docker vs SDK: Different Tools for Different Needs
Atlassian Docker images provide several advantages that complement the SDK approach:
- Production-like environments: Docker images mirror actual Atlassian Cloud infrastructure more closely
- Faster startup times: No compilation needed - containers spin up in seconds
- Resource efficiency: Better isolation and resource management
- Version flexibility: Easy switching between exact Atlassian versions
- Scalability: Can simulate multiple instances or cluster configurations
When to Consider Docker Images
Docker images particularly shine for:
- Infrastructure testing: Validating deployment configurations
- Performance testing: Load testing with production-like setups
- Integration testing: Multi-service architectures with databases, proxies, etc.
- CI/CD pipelines: Automated testing environments
- Team collaboration: Consistent environments across development teams
The Docker + ngrok Combination
Similar to our SDK approach, Docker containers can be exposed via ngrok:
# Example workflow (simplified)
docker run -p 8080:8080 atlassian/confluence-server:latest
ngrok http http://localhost:8080
This approach would eliminate the compilation overhead of the SDK while maintaining the rapid testing benefits of ngrok exposure.
Why This Post Focuses on SDK
For this particular guide, we chose the Atlassian SDK approach because:
- Developer familiarity: Most Atlassian developers already have SDK experience
- Plugin development: SDK provides better integration for custom plugin testing
- Configuration flexibility: Easier to modify JVM parameters and development settings
- Quick reload capabilities: Hot-swapping of plugin code during development
- Established toolchain: Well-documented maven-based workflow
Future Exploration
The Docker + ngrok approach deserves its own detailed exploration, particularly for:
- DevOps teams focused on infrastructure and deployment
- QA teams needing production-like test environments
- Organizations prioritizing containerized development workflows
Both approaches—SDK and Docker—offer unique advantages for different aspects of Atlassian migration testing. The key is choosing the right tool for your specific testing objectives and team expertise.
