Liferay Upgrade Tool

Purpose & User Intent: The tool solves the problem of planning, validating, and accelerating upgrades of Liferay codebases across versions. Target users are DevOps engineers, platform architects, and IT teams responsible for portal upgrades and module migrations. When upgrading a portal, particularly across major versions or when replacing deprecated APIs, the tool helps determine tasks, dependencies, and risk before any code change is applied. The focus is on domain logic, upgrade viability, and predictable outcomes rather than user interface flow. It is designed for enterprise contexts with multi module apps and custom liferay modules.
Core Logic & Features: Required capabilities include 1) Version compatibility analysis between current and target Lifera versions with module level checks; 2) Migration plan generation detailing tasks, owners, precedence, and estimated effort; 3) Risk scoring based on API deprecations, API changes, and test coverage; 4) Change impact reporting highlighting affected modules and suggested remediation. Optional features include 5) Dependency graph export for CI integration; 6) Auto generation of patch templates or migration scripts; 7) Release notes driven delta summaries. The tool enforces a clear workflow where core features are mandatory inputs for every upgrade scenario, while optional features augment the plan when data sources exist.
Inputs & Outputs: Inputs include current_version string e.g. 7.4.3, target_version string e.g. 8.0.0, codebase_path string, modules array of strings, include_plugins boolean, and optional data sources such as repository access token and test results. Outputs include migration_plan structured JSON, risk_score 0 100, delta_report text, compatibility_matrix CSV, and a final exportable_upgrade_report JSON or PDF. Validation rules verify version syntax, ensure codebase_path accessibility, verify module references, and check optional data presence if provided.
Algorithms & Calculations: The tool references an internal compatibility matrix and release note indexing to assess compatibility between versions. It calculates risk_score from weighted factors API deprecations breaking changes module compatibility and test coverage. It sorts upgrade tasks by dependency and estimates total effort. The delta_report summarizes changes by module and API surface, while the plan includes actionable tasks with owners and due dates when supplied.
Error & Edge Cases: Missing required inputs triggers explicit errors; unknown versions fall back to conservative guidance; if release notes or data sources are unavailable, the tool generates partial plans with caveats. For very large codebases, it proposes phased upgrades and task batching. If repository access or authentication fails, it reports credential requirements and suggests remediation.
Industry/Region & Localization: Uses standard Liferay versioning conventions, supports UTC timestamps in reports, and records locale neutral identifiers unless locale data is supplied. It assumes enterprise deployment norms and can adapt to region specific compliance where applicable.
Assumptions & Exclusions: Assumes conventional repository layout and build tooling; does not apply patches, execute deployments, or perform runtime tests; excludes user interface provisioning, collaboration features, or non code upgrade activities; it focuses exclusively on upgrade planning, risk assessment, and task generation.
