+# Backport Summary: PR #144 Fix to Release Branches
+
+## Overview
+This document summarizes the backport of PR #144 fix (duplicate livenessProbe in key-manager deployment) to release branches 4.6.x, 4.5.x, and 4.4.x.
+
+## Fix Description
+The key-manager deployment template contained two `livenessProbe` definitions where the second should have been a `readinessProbe`.
+
+**Changes Made:**
+- Changed the second probe definition from `livenessProbe` to `readinessProbe`
+- Updated configuration references to use `.Values.wso2.deployment.readinessProbe.*` instead of `.Values.wso2.deployment.livenessProbe.*`
+
+## Implementation Details
+
+The fix has been prepared and tested for all three release branches. Local feature branches have been created with the necessary changes:
+
+### Branch: 4.6.x
+- **Local Feature Branch:** `copilot/backport-fix-to-4.6.x`
+- **Base Branch:** `4.6.x` (commit: eb36edc)
+- **Commit:** 358ce5a
+- **File:** `distributed/key-manager/templates/key-manager/wso2am-km-deployment.yaml`
+- **Lines Changed:** 163-169
+- **Helm Lint:** ✅ Passed
+
+### Branch: 4.5.x
+- **Local Feature Branch:** `copilot/backport-fix-to-4.5.x`
+- **Base Branch:** `4.5.x` (commit: a5ace5d)
+- **Commit:** 086c5ce
+- **File:** `distributed/key-manager/templates/key-manager/wso2am-km-deployment.yaml`
+- **Lines Changed:** 120-126
+- **Helm Lint:** ✅ Passed
+
+### Branch: 4.4.x
+- **Local Feature Branch:** `copilot/backport-fix-to-4.4.x`
+- **Base Branch:** `4.4.x` (commit: 16c14e9)
+- **Commit:** a296732
+- **File:** `distributed/key-manager/templates/key-manager/wso2am-km-deployment.yaml`
+- **Lines Changed:** 89-95
+- **Helm Lint:** ✅ Passed
+
+## Patch Files
+
+To apply these changes, use the following patch commands for each branch:
+
+### For 4.6.x:
+```bash
+git checkout 4.6.x
+git cherry-pick 358ce5a
+# Or apply the patch manually (see below)
+```
+
+### For 4.5.x:
+```bash
+git checkout 4.5.x
+git cherry-pick 086c5ce
+# Or apply the patch manually (see below)
+```
+
+### For 4.4.x:
+```bash
+git checkout 4.4.x
+git cherry-pick a296732
+# Or apply the patch manually (see below)
+```
+
+## Manual Patch (applicable to all branches)
+
+In `distributed/key-manager/templates/key-manager/wso2am-km-deployment.yaml`, find the duplicate `livenessProbe` sections and change:
+
+```yaml
+        livenessProbe:
+          httpGet:
+              path: /services/Version
+              port: {{ add 9763 .Values.wso2.apim.portOffset }}
+          initialDelaySeconds: {{ .Values.wso2.deployment.livenessProbe.initialDelaySeconds }}
+          periodSeconds: {{ .Values.wso2.deployment.livenessProbe.periodSeconds }}
+          failureThreshold: {{ .Values.wso2.deployment.livenessProbe.failureThreshold }}
+        livenessProbe:  # <-- This is the duplicate that needs to be changed
+          httpGet:
+              path: /services/Version
+              port: {{ add 9763 .Values.wso2.apim.portOffset }}
+          initialDelaySeconds: {{ .Values.wso2.deployment.livenessProbe.initialDelaySeconds }}
+          periodSeconds: {{ .Values.wso2.deployment.livenessProbe.periodSeconds }}
+          failureThreshold: {{ .Values.wso2.deployment.livenessProbe.failureThreshold }}
+```
+
+To:
+
+```yaml
+        livenessProbe:
+          httpGet:
+              path: /services/Version
+              port: {{ add 9763 .Values.wso2.apim.portOffset }}
+          initialDelaySeconds: {{ .Values.wso2.deployment.livenessProbe.initialDelaySeconds }}
+          periodSeconds: {{ .Values.wso2.deployment.livenessProbe.periodSeconds }}
+          failureThreshold: {{ .Values.wso2.deployment.livenessProbe.failureThreshold }}
+        readinessProbe:  # <-- Changed from livenessProbe to readinessProbe
+          httpGet:
+              path: /services/Version
+              port: {{ add 9763 .Values.wso2.apim.portOffset }}
+          initialDelaySeconds: {{ .Values.wso2.deployment.readinessProbe.initialDelaySeconds }}  # <-- Changed reference
+          periodSeconds: {{ .Values.wso2.deployment.readinessProbe.periodSeconds }}  # <-- Changed reference
+          failureThreshold: {{ .Values.wso2.deployment.readinessProbe.failureThreshold }}  # <-- Changed reference
+```
+
+## Verification
+
+All changes have been verified:
+1. ✅ Syntax is correct (YAML formatting)
+2. ✅ Helm lint passes for all branches
+3. ✅ Changes match the original PR #144 fix
+4. ✅ readinessProbe configuration references correct values
+5. ✅ All three branches have been tested locally
+
+## Next Steps
+
+To complete the backport:
+1. Push the local feature branches to remote (requires appropriate permissions)
+2. Create pull requests for each branch:
+   - `copilot/backport-fix-to-4.6.x` → `4.6.x`
+   - `copilot/backport-fix-to-4.5.x` → `4.5.x`
+   - `copilot/backport-fix-to-4.4.x` → `4.4.x`
+3. Review and merge the PRs

+# How to Apply the Backport Fixes
+
+This directory contains patch files for backporting the PR #144 fix to release branches 4.6.x, 4.5.x, and 4.4.x.
+
+## Option 1: Using Local Branches (Recommended)
+
+If you have access to the repository with the local branches still available:
+
+```bash
+# For 4.6.x
+git push origin copilot/backport-fix-to-4.6.x
+
+# For 4.5.x
+git push origin copilot/backport-fix-to-4.5.x
+
+# For 4.4.x
+git push origin copilot/backport-fix-to-4.4.x
+```
+
+Then create PRs through the GitHub interface:
+- `copilot/backport-fix-to-4.6.x` → `4.6.x`
+- `copilot/backport-fix-to-4.5.x` → `4.5.x`
+- `copilot/backport-fix-to-4.4.x` → `4.4.x`
+
+## Option 2: Using Patch Files
+
+If the local branches are not available, you can apply the patches directly:
+
+### For 4.6.x:
+```bash
+git checkout 4.6.x
+git checkout -b fix/backport-pr144-to-4.6.x
+git apply patches/fix-duplicate-livenessprobe-4.6.x.patch
+git add .
+git commit -m "Fix duplicate livenessProbe in key-manager deployment
+
+Backport of PR #144 fix to 4.6.x branch"
+git push origin fix/backport-pr144-to-4.6.x
+```
+
+### For 4.5.x:
+```bash
+git checkout 4.5.x
+git checkout -b fix/backport-pr144-to-4.5.x
+git apply patches/fix-duplicate-livenessprobe-4.5.x.patch
+git add .
+git commit -m "Fix duplicate livenessProbe in key-manager deployment
+
+Backport of PR #144 fix to 4.5.x branch"
+git push origin fix/backport-pr144-to-4.5.x
+```
+
+### For 4.4.x:
+```bash
+git checkout 4.4.x
+git checkout -b fix/backport-pr144-to-4.4.x
+git apply patches/fix-duplicate-livenessprobe-4.4.x.patch
+git add .
+git commit -m "Fix duplicate livenessProbe in key-manager deployment
+
+Backport of PR #144 fix to 4.4.x branch"
+git push origin fix/backport-pr144-to-4.4.x
+```
+
+## Option 3: Manual Application
+
+See [BACKPORT_SUMMARY.md](../BACKPORT_SUMMARY.md) for detailed instructions on manually applying the fix.
+
+## Verification
+
+After applying the patches, verify with:
+```bash
+helm lint distributed/key-manager
+```
+
+All patches have been pre-verified and pass helm lint checks.
