+## Mirror Migration for New CloudLinux Versions
+
+This section explains why the old mirror system will not support newer CloudLinux OS/package versions, and how to migrate to the new mirror configuration.
+
+[[toc]]
+
+## Summary
+
+New CloudLinux versions are moving to the new mirror service and open HTTPS mirrors. The legacy mirror system (custom SSL/XMLRPC) will not support newer OS and package versions. Customers should reconfigure their mirrors to the new standard HTTPS layout and endpoint.
+
+**Currently, only CloudLinux OS 10 is supported**, and support for older versions will be enabled gradually.
+
+For customer-managed mirrors, the migration means **adding a new HTTPS mirror** (or **replacing** the legacy mirror endpoint) rather than "reconfiguring". In most cases you can **reuse existing storage** and just adjust the mirror layout/paths and transport (open HTTPS).
+
+## What is changing
+
+- Legacy mirrors used custom SSL and XMLRPC transport.
+- New mirrors use standard HTTPS and normal directory browsing.
+- The mirrorlist endpoint is now `cl-mirrors` (not `cln-mirrors`).
+- The new system supports partial mirrors (only the OS versions you need).
+
+## Why the old system will not work for newer versions
+
+- Newer CloudLinux tooling uses the **new mirrorlist endpoint** (`cl-mirrors`) and standard HTTPS mirrors.
+- The legacy XMLRPC/custom SSL flow is being phased out.
+- Mirrors that only support the old endpoint (`cln-mirrors`) may not be selected by updated systems.
+
+## What you need to do (migration quick plan)
+
+1. **Set up a new HTTPS mirror** that exposes SWNG content via standard HTTPS.
+2. **Use the new mirrorlist endpoint**:
+   - `https://repo.cloudlinux.com/cloudlinux/mirrorlists/cl-mirrors`
+3. **Optionally mirror only the versions you need** (partial mirrors are supported).
+4. **Provide your mirror URL and scope** to CloudLinux support so it can be added to mirror rotation.
+
+:::tip
+- SWNG is the main operational repository for updates.
+- `repo.cloudlinux.com` contains conversion and install assets.
+- Full `repo.cloudlinux.com` is large (>3 TB), so partial sync is recommended unless you need a fully autonomous environment.
+:::
+
+## Creating a CloudLinux Mirror (SWNG)
+
+### Minimum requirements for a supported mirror
+
+Your mirror should meet these requirements to be eligible for inclusion in the mirror service:
+
+- **HTTPS access** with a valid certificate from a public CA (e.g., Let's Encrypt)
+- **Correct base paths** (recommended layout):
+  - `https://mirror.example.com/swng/` for SWNG
+  - (optional) `https://mirror.example.com/cloudlinux/` for `repo.cloudlinux.com` content
+- **No authentication** for repository downloads
+- **Repository metadata is accessible** (e.g., `repodata/repomd.xml` for the mirrored trees)
+- **Regular sync schedule** (cron/systemd timer) and enough disk space for the chosen scope
+
+### Step-by-step: mirror SWNG
+
+**1. Prepare storage**
+
+Use a dedicated disk or partition. Plan for approximately 500 GB for SWNG.
+
+**2. Sync SWNG**
+
+Use rsync from the upstream endpoint:
+
+```
+# Example: mirror all SWNG
+rsync -avH --delete --numeric-ids --safe-links \
+  rsync://rsync.upstream.cloudlinux.com/SWNG/ \
+  /var/www/mirrors/swng/
+```
+
+If you only need specific versions, mirror only those subpaths (partial mirrors):
+
+```
+# Example: mirror CloudLinux 10 SWNG only
+mkdir -p /var/www/mirrors/swng/10
+rsync -avH --delete --numeric-ids --safe-links \
+  rsync://rsync.upstream.cloudlinux.com/SWNG/10/ \
+  /var/www/mirrors/swng/10/
+```
+
+**3. Expose via HTTPS**
+
+Configure Nginx (or another web server). Enable directory browsing and ensure HTTPS works with a valid certificate.
+
+**4. Validate the public index**
+
+Ensure the index matches the upstream structure. Mixed setups can use `<domain>/swng/`.
+
+### Optional: mirror `repo.cloudlinux.com` content
+
+Use this only if you need a fully autonomous install/conversion environment:
+
+- Full sync is **3+ TB**.
+- In most cases, sync only the required sub-repositories.
+
+If you decide to mirror it, use the upstream rsync module:
+
+```
+rsync -avH --delete --numeric-ids --safe-links \
+  rsync://rsync.upstream.cloudlinux.com/CLOUDLINUX/ \
+  /var/www/mirrors/cloudlinux/
+```
+
+### Information to provide to CloudLinux Support
+
+When contacting CloudLinux Support to register your mirror, provide:
+
+- Mirror URL (HTTPS), e.g. `https://mirror.example.com/swng/`
+- Whether the mirror is **public** or **private**
+- For private mirrors: list of IPs or networks
+- Geographic location (country/city)
+- Available bandwidth/capacity
+- Sync method and frequency
+- Whether the mirror is **complete** or **partial**
+- If partial: list the versions mirrored
+
+## Self-diagnostics (mirror server)
+
+This section helps you verify your mirror is healthy before contacting Support.
+
+### Connectivity to upstream
+
+```
+# DNS resolution
+nslookup upstream.cloudlinux.com
+
+# HTTPS connectivity (for browsing)
+curl -fsSI https://upstream.cloudlinux.com/ | head
+
+# RSync endpoint listing (should return module list)
+rsync rsync://rsync.upstream.cloudlinux.com/
+```
+
+If you are behind a corporate proxy/firewall, ensure outbound access from the mirror host:
+- TCP **873** to `rsync.upstream.cloudlinux.com` (rsync)
+- TCP **443** to `upstream.cloudlinux.com` (HTTPS browsing/validation)
+
+### RSync checks
+
+```
+# Dry-run a small test sync (replace path as needed)
+mkdir -p /tmp/cl-mirror-test
+rsync -avv --delete rsync://rsync.upstream.cloudlinux.com/SWNG/10/ /tmp/cl-mirror-test/ | head -n 50
+```
+
+Common rsync pitfalls:
+- `@ERROR: ...` typically indicates connectivity/firewall/proxy issues.
+- Slow sync is often disk I/O bottlenecks or too frequent `--delete` on huge trees; use a reasonable sync interval.
+
+### HTTPS checks (your mirror)
+
+Replace `mirror.example.com` with your mirror domain.
+
+```
+# Mirror root must be reachable via HTTPS
+curl -fsSI "https://mirror.example.com/swng/" | head
+
+# Metadata must exist for mirrored subtrees (example for CL10 x86_64)
+curl -fsSI "https://mirror.example.com/swng/10/x86_64/repodata/repomd.xml" | head
+```
+
+If you use a different layout (e.g., you expose SWNG at `/`), adjust paths accordingly. Trailing slashes matter for some web server configurations.
+
+### Storage, permissions, and sync hygiene
+
+```
+# Disk space
+df -h
+
+# Basic directory permissions (adjust path to your mirror root)
+ls -ld /var/www/mirrors /var/www/mirrors/swng
+
+# Check that new files are appearing after a sync run (example)
+ls -lh /var/www/mirrors/swng/10/ | head
+```
+
+Recommendations:
+- Run sync as a dedicated user that can write to the destination directory.
+- Ensure your HTTPS server can read the mirrored files.
+- Keep sync logs (cron output or systemd journal) so you can share errors with Support.
+
+## Troubleshooting
+
+| Issue | Fix |
+|-------|-----|
+| **Firewall blocks RSync/HTTPS** | Outbound from mirror host: TCP `873` (rsync) and `443` (HTTPS). Inbound to your mirror (for clients): TCP `443` (HTTPS). |
+| **DNS fails to resolve** | Verify `/etc/resolv.conf`, corporate DNS rules. Run `nslookup upstream.cloudlinux.com`. |
+| **RSync not installed** | Install `rsync` with your package manager, then retry the sync. |
+| **Mirror returns 403/404** | Confirm the exact base paths and trailing slashes. Confirm your web server maps URLs to the correct filesystem directories. Reference: `https://upstream.cloudlinux.com/swng/` and `https://upstream.cloudlinux.com/cloudlinux/` |
+| **Insufficient disk space** | Run `df -h` and sync only the required sub-repositories. |
+| **Permission errors** | Ensure the sync user can write to the destination directory. |
+| **Certificate problems** | Renew or replace the certificate (Let's Encrypt auto-renewal recommended). |
+| **Partial mirror not in mirrorlist** | Confirm the mirrored versions match the scope provided to Support. For private mirrors, confirm egress IPs match the scope. Changes may take time to propagate. |
+
+### Connection issues
+
+```
+# Test RSync connectivity
+rsync rsync://rsync.upstream.cloudlinux.com/
+
+# Test HTTP connectivity
+curl -I https://upstream.cloudlinux.com/
+
+# Check DNS resolution
+nslookup upstream.cloudlinux.com
+```
+
+### Sync failures
+
+```
+# Test with verbose output
+rsync -avv --delete rsync://rsync.upstream.cloudlinux.com/CLOUDLINUX/ /tmp/test-sync/
+
+# Check disk space
+df -h
+```
