<!-- This is the upgrade summary generated after successful completion of the Azure SDK migration. It documents the final results, changes made, and lessons learned.

SUMMARY RULES

!!! DON'T REMOVE THIS COMMENT BLOCK BEFORE UPGRADE IS COMPLETE AS IT CONTAINS IMPORTANT INSTRUCTIONS.

Prerequisites (must be met before generating summary)

• All steps in plan.md have ✅ in progress.md
• Final Validation step completed successfully

Success Criteria Verification

• Goal: All legacy Azure SDK dependencies (com.microsoft.azure.*) replaced with modern equivalents (com.azure.*)
• Compilation: Both main AND test code compile = mvn clean test-compile succeeds
• Test: 100% pass rate = mvn clean test succeeds (or ≥ baseline with documented pre-existing flaky tests)

Content Guidelines

• Upgrade Result: MUST show 100% pass rate or justify EACH failure with exhaustive documentation
• Tech Stack Changes: Table with Dependency | Before | After | Reason
• Commits: List with IDs and messages from each step
• Challenges: Key issues and resolutions encountered
• Limitations: Only genuinely unfixable items where: (1) multiple fix approaches attempted, (2) root cause identified, (3) technically impossible to fix
• Next Steps: Recommendations for post-upgrade actions

Efficiency (IMPORTANT)

• Targeted reads: Use grep over full file reads; read specific sections from progress.md, not entire files.

Upgrade Result

<!-- Compare final compile/test results against baseline. MUST show 100% pass rate or justify EACH failure with exhaustive documentation.

SAMPLE:

Upgrade Goals Achieved:

• ✅ All com.microsoft.azure.* dependencies replaced with com.azure.* equivalents
• ✅ Source code migrated to modern Azure SDK APIs

-->

Upgrade Goals Achieved:

Tech Stack Changes

<!-- Table documenting all dependency changes made during the upgrade. Only include dependencies that were actually changed.

SAMPLE:

-->

Commits

<!-- List all commits made during the upgrade with their short IDs and messages.

SAMPLE:

-->

Challenges

<!-- Document key challenges encountered during the upgrade and how they were resolved.

SAMPLE:

• Authentication Migration
• Issue: Legacy code uses Azure.authenticate(credentialFile) which has no direct equivalent in modern SDK.
• Resolution: Read credential file with Jackson ObjectMapper, construct ClientSecretCredential, use AzureProfile.
• Files Changed: AzureHelper.java, AppConfig.java

• Fluent API Changes
• Issue: Method names differ between legacy Azure.management and modern azure-resourcemanager.
• Resolution: Followed migration guide at https://aka.ms/java-track2-migration-guide
• Files Changed: ResourceProvisioner.java, StorageSetup.java

-->

Limitations

<!-- Document any genuinely unfixable limitations that remain after the upgrade. This section should be empty if all issues were resolved. Only include items where: (1) multiple fix approaches were attempted, (2) root cause is identified, (3) fix is technically impossible without breaking other functionality. -->

Review Code Changes Summary

<!-- Document review code changes results from the upgrade. This section ensures the upgrade is both sufficient (complete) and necessary (no extraneous changes), with original functionality and security controls preserved.

VERIFICATION AREAS:

1. Sufficiency: All required upgrade changes are present — no missing modifications
2. Necessity: All changes are strictly necessary — no unnecessary modifications, including:

• Functional Behavior Consistency: Business logic, API contracts, expected outputs
• Security Controls Preservation (critical subset of behavior):
• Authentication: Login mechanisms, session management, token validation, MFA configurations
• Authorization: Role-based access control, permission checks, access policies, security annotations (@PreAuthorize, @Secured, etc.)
• Password handling: Password encoding/hashing algorithms, password policies, credential storage
• Security configurations: CORS policies, CSRF protection, security headers, SSL/TLS settings, OAuth/OIDC configurations
• Audit logging: Security event logging, access logging

SAMPLE (no issues): Review Status: ✅ All Passed

Sufficiency: ✅ All required upgrade changes are present Necessity: ✅ All changes are strictly necessary

• Functional Behavior: ✅ Preserved — business logic, API contracts unchanged
• Security Controls: ✅ Preserved — authentication, authorization, password handling, security configs, audit logging unchanged

SAMPLE (with behavior changes): Review Status: ⚠️ Changes Documented Below

Sufficiency: ✅ All required upgrade changes are present

Necessity: ⚠️ Behavior changes required by SDK migration (documented below)

• Functional Behavior: ✅ Preserved
• Security Controls: ⚠️ Changes made with equivalent protection

-->

Next Steps

<!-- Recommendations for post-upgrade actions.

SAMPLE:

• [ ] Run full integration test suite in staging environment
• [ ] Performance testing to validate no regression
• [ ] Update CI/CD pipelines if dependency versions changed
• [ ] Update documentation to reflect new Azure SDK versions
• [ ] Review azure-sdk-bom version periodically for updates
