+# CKAN 2.11 Migration Progress
+
+## Starting Point
+- Extension: ckanext-versions
+- Target: CKAN 2.11 + Python 3.10
+- Branch: toavina/update-python
+
+## Initial Setup
+
+### Update GitHub Actions Workflow
+**File Modified**: `.github/workflows/test.yml`
+
+**Changes**:
+- Updated GitHub Actions from v2 → v6
+- Removed matrix strategy for multiple Python/CKAN versions
+- Set single Python version: "3.10"
+- Set single CKAN version: 2.11
+- Container: `ckan/ckan-dev:2.11-py3.10` with `--user root` option
+- Updated services to CKAN 2.11 versions:
+  - Solr: `ckan/ckan-solr:2.11-solr9`
+  - Postgres: `ckan/ckan-postgres-dev:2.11`
+  - Redis: `redis:3`
+- Simplified test run command (removed codecov upload)
+
+**Result**: Ready for testing with CKAN 2.11
+
+---
+
+## Fix 1: Activity Model Import
+
+### Issue
+**Error**: Setup extension failed with:
+```
+ModuleNotFoundError: No module named 'ckan.model.activity'
+AttributeError: module 'ckan.model' has no attribute 'Activity'
+```
+
+**Location**:
+- `ckanext/versions/logic/action.py:17-19`
+- `ckanext/versions/logic/dataset_version_action.py:13-16`
+
+### Root Cause
+Starting from CKAN 2.10, activities were extracted into a separate plugin. The Activity model class was moved from `ckan.model.Activity` to `ckanext.activity.model.Activity`.
+
+**References**:
+- [Extract activities into a separate plugin - PR #6790](https://github.com/ckan/ckan/pull/6790)
+- [CKAN 2.9 to 2.10 migration tips](https://github.com/ckan/ckan/wiki/CKAN-2.9-to-2.10-migration-tips)
+
+### Solution Applied
+Updated the import fallback chain to try the CKAN 2.10+ pattern first:
+```python
+# Activity import for different CKAN versions
+# CKAN 2.10+ moved Activity to a separate plugin
+try:
+    from ckanext.activity.model import Activity
+except ImportError:
+    try:
+        from ckan.model import Activity
+    except ImportError:
+        Activity = core_model.Activity
+```
+
+This provides backward compatibility with CKAN <=2.9 while supporting CKAN 2.10+.
+
+**Files Modified**:
+- `ckanext/versions/logic/action.py`: Lines 15-23
+- `ckanext/versions/logic/dataset_version_action.py`: Lines 12-20
+
+**Result**: Ready for testing
+
+---
+
+## Testing Status
+- Initial test: Setup extension failed (Activity import error)
+- After Fix 1: Test completed - 80 failed, 11 passed, 12 errors
+
+---
+
+## Fix 2: Auth Function Registration Bug
+
+### Issue
+**Error**: Multiple tests failing with:
+```
+ValueError: Authorization function not found: version_create
+ValueError: Authorization function not found: version_delete
+ValueError: Authorization function not found: version_list
+ValueError: Authorization function not found: version_show
+```
+
+**Location**: `ckanext/versions/plugin.py:71`
+
+### Root Cause
+In the `get_auth_functions()` method, the `resource_version_clear` auth function was incorrectly registered as `action.resource_version_clear` instead of `auth.resource_version_clear`. This caused the auth module to not be properly initialized, preventing all auth functions from being registered.
+
+### Solution Applied
+Changed line 71 in plugin.py from:
+```python
+'resource_version_clear': action.resource_version_clear,
+```
+to:
+```python
+'resource_version_clear': auth.resource_version_clear,
+```
+
+**Files Modified**:
+- `ckanext/versions/plugin.py`: Line 71
+
+**Result**: Auth functions should now register correctly. However, tests still show auth functions not found.
+
+---
+
+## Fix 3: Add clean_db_with_migrations fixture for CKAN 2.11 activity plugin
+
+### Issue
+**Error**: 2 tests in test_helpers.py failing with:
+```
+sqlalchemy.exc.ProgrammingError: column "permission_labels" of relation "activity" does not exist
+```
+
+**Root Cause**:
+Similar to ckanext-fork and ckanext-restricted, CKAN 2.11's activity plugin requires a `permission_labels` column in the activity table. The `clean_db` fixture rebuilds the database fresh for test isolation, but doesn't include plugin-specific migrations.
+
+### Solution Applied
+Created a `clean_db_with_migrations` fixture (following pattern from PROGRESS_FORK.md):
+
+1. Added fixture to `ckanext/versions/tests/fixtures.py`:
+   - Extends the standard `clean_db` fixture
+   - After `clean_db` runs, manually executes SQL to add the `permission_labels` column:
+     ```sql
+     ALTER TABLE activity ADD COLUMN IF NOT EXISTS permission_labels text[];
+     ```
+
+2. Updated `test_helpers.py` to use `clean_db_with_migrations` instead of `clean_db`
+
+**Files Modified**:
+- `ckanext/versions/tests/fixtures.py`: Added `clean_db_with_migrations` fixture
+- `ckanext/versions/tests/test_helpers.py`: Changed fixtures from `clean_db` to `clean_db_with_migrations`
+
+**Result**: Should fix the 2 permission_labels errors. Auth function issue still unresolved. Ready for testing.
+
+---
+
+## Migration Status: INCOMPLETE
+
+### Test Results Summary
+- **Before fixes**: 80 failed, 11 passed, 12 errors
+- **After Fix 2 & 3**: Not tested - migration abandoned due to complexity
+
+### Issues Identified
+
+1. **Auth Function Registration Bug (Fix 2)** ✅ Fixed in code, but not verified
+   - Found and fixed bug on plugin.py:71 where `action.resource_version_clear` was incorrectly registered as auth function
+   - However, tests still showed "Authorization function not found" errors for all auth functions
+   - Root cause unclear - may be deeper plugin initialization issue in CKAN 2.11
+
+2. **Permission Labels Column (Fix 3)** ✅ Fixed in code, but not verified
+   - Added `clean_db_with_migrations` fixture following pattern from ckanext-fork
+   - Should resolve 2 errors in test_helpers.py
+
+3. **Unresolved Issues**:
+   - 80 tests still failing with "Authorization function not found"
+   - Missing CKAN actions: `package_activity_list`, `activity_data_show` (renamed/removed in CKAN 2.11)
+   - View plugin issues: `versions_view`, `image_view` not found
+   - Auth functions not accessible despite correct registration
+   - Likely requires more extensive refactoring than other extensions
+
+### Why Migration Was Abandoned
+
+This extension proved significantly more complex than ckanext-fork (14 fixes, 61 tests) or ckanext-restricted (10 fixes, 24 tests). The auth function registration issue suggests deeper architectural incompatibility with CKAN 2.11 that would require:
+- Extensive debugging of plugin initialization
+- Possibly redesigning how auth functions are registered
+- Understanding why 11 tests pass but 80 fail with same auth error
+- Time investment exceeding available resources
+
+### Recommendation
+
+Future migration attempts should:
+1. Verify plugin loading and auth registration work before addressing individual test failures
+2. Consider whether the extension's architecture is compatible with CKAN 2.11's plugin system changes
+3. Budget significantly more time than simpler extensions (estimate 3-4x the effort of ckanext-fork)
+4. May require upstream consultation with CKAN community about auth function registration changes in 2.11
+
+### Files Modified (Not Fully Tested)
+- `.github/workflows/test.yml` - Updated to CKAN 2.11
+- `ckanext/versions/logic/action.py` - Activity model import compatibility
+- `ckanext/versions/logic/dataset_version_action.py` - Activity model import compatibility
+- `ckanext/versions/plugin.py` - Fixed auth function registration bug
+- `ckanext/versions/tests/fixtures.py` - Added clean_db_with_migrations fixture
+- `ckanext/versions/tests/test_helpers.py` - Use clean_db_with_migrations
+- `PROGRESS.md` - Documentation
