More details

The App Compatibility Scanner (ACS) helps Data Center administrators plan upgrades with confidence by automatically scanning installed apps for compatibility issues with target product versions.

Key Features:

Java API Compatibility Scanning: Detects when apps use Java APIs that have been removed, modified, or deprecated in newer product versions, including class, method, constructor, and field-level changes.
REST API Compatibility Scanning: Analyzes app frontend code for REST API calls that may break due to endpoint removals, method changes, or request body incompatibilities in newer versions.
Dependency Analysis: Identifies bundled library conflicts between app dependencies and product-provided packages.
Multi-Version Support: Compare app compatibility across multiple Jira and Confluence versions simultaneously.
Detailed Reporting: Get clear, actionable reports highlighting specific incompatibilities with links to relevant documentation and migration guides.
