What This Plugin Adds

Migration Assistant is an Available, Schema-owning Capell package in the Capell Operations product group. It ships as capell-app/migration-assistant and extends these surfaces: admin, console.

Migration Assistant adds staged import sessions for mapping, validating, executing, reviewing, retrying, and rolling back external content imports.

Admins can upload or select source data, map it to Capell records, validate the plan, run the import, and inspect row-level results.

Status details:

Status: Available
Tier: free
Bundle: operations
Composer package: capell-app/migration-assistant
Namespace: Capell\MigrationAssistant
Theme key: not applicable

Why It Matters

For developers: Source, target, and executor registries keep import formats and destinations replaceable while Actions own validation, authorization, recovery, and rollback.

For teams: Teams can review migration problems before content is written and keep a recovery path when an import needs to be undone.

Data Model

Required tables: import_sessions, import_rollback_reports, import_rollback_audits.
Models: ImportRollbackAudit, ImportRollbackReport, ImportSession.
Core record references in migrations: users via user_id.
Migration files: 2026_05_10_190859_01_create_import_sessions_table.php, 2026_05_10_190859_02_create_import_rollback_reports_table.php, 2026_06_04_000001_rename_import_rollback_reports_table.php, 2026_07_10_000002_encrypt_import_diagnostics.php, 2026_07_10_120000_harden_import_rollback_provenance.php.
Migration impact: run host migrations through the package install flow before opening package surfaces.
Deletion/retention behaviour: migrations declare cascade-on-delete relationships and null-on-delete relationships; no timed pruning or retention schedule is declared in capell.json.

Install Impact

Required packages: capell-app/admin, capell-app/core.
Admin navigation: declares admin-page: ImportPagesPageContribution, admin-page: ImportSitesPageContribution, admin-resource: ImportSessionResourceContribution; each Filament page or resource controls its own navigation visibility.
Admin/editor extensions: none declared.
Permissions: page.export, page.import, page.import.update-shared-relations, page.import.publish-live, import-session.view, import-session.cancel, import-session.retry, import-session.rollback; Shield-generated page permissions for Capell\MigrationAssistant\Filament\Pages\ImportPagesPage (names and grants depend on host Shield configuration); access also governed by package policies: ImportSessionPolicy.
Public routes: none declared.
Database changes: package migrations are declared.
Config: config/migration-assistant.php.
Settings: no package settings declared.
Queues or schedules: scheduled commands migration-assistant:reclaim-stale (everyTenMinutes; manifest declared); queue jobs ExecuteImportPlanJob.
Cache tags: none declared.
Commands: migration-assistant:export, migration-assistant:import, migration-assistant:rollback-execute, migration-assistant:rollback-report, migration-assistant:status.

Common Pitfalls

Keep required Capell packages on compatible v4 releases: capell-app/admin, capell-app/core.
Run migrations before opening package resources or public routes.
Review package configuration before production-like verification: config/migration-assistant.php.
Keep the host Laravel scheduler running so package-registered schedules can execute: migration-assistant:reclaim-stale (everyTenMinutes; manifest declared).

Troubleshooting

Symptom	Likely cause	Check	Fix
Package surface is missing after install	Provider or manifest is not loaded	Confirm `capell.json`, package `composer.json`, and provider registration	Reinstall the package, refresh Composer autoload, and clear host caches
Admin screen or command fails on missing table	Package migrations have not run	Check the tables listed in `Data Model`	Run host migrations and rerun the focused package test
Background work does not run	Queue worker or declared schedule is not active	Check the jobs and scheduled commands listed in `Technical Shape`	Start the queue worker or host scheduler, then run the focused command or package test

Quick Start

Install the package: composer require capell-app/migration-assistant.
Open the package admin surface at /admin/migration-assistant/import-sessions and confirm Migration Assistant is available.
