+title: 'Exporting SCALE App config only'
+---
+
+With the removal of kubernetes-based TrueNAS SCALE Apps and the discontinuation of our TrueNAS SCALE App catalog, We understand users want to be looking to move to other solutions.
+We've had a lot of users request guidance on how to export the SCALE App configuration, so they can copy-paste parts of it into other solutions, such as Docker-Compose or iX-Systems SCALE Apps.
+
+As part of your ClusterTool project, we've, for this usercase, implemented 2 commands to export and clean-up the whole configuration of the Apps as intered in the GUI.
+Into neatly structured YAML files. From which users can easily copy-paste into, for example, a docker-compose file.
+
+
+## Pre-Migrations Advisory
+
+Prior to migration, we require the following to be done:
+
+### **DO NOT** update to Electric Eel
+
+As soon as you migupdaterated to TrueNAS SCALE 24.10 "Electric Eel", you cannot, in any way, migrate your TrueCharts Apps anymore.
+
+
+### Install ClusterTool
+
+Ensure the Clustertool binary is downloaded into a folder on your TrueNAS SCALE Machine, all exports will be output into this folder.
+
+### Note on  storage
+
+Storage and data stored within apps is not included with this export.
+The tool will just provide a clean export of the configuration you entered into the GUI.
+
+For access to PVC-based datastores, we advice the use of HeavyScript instead.
+
+
+## Important note
+
+We do not sanitise the exported/migated configuration from SCALE.
+We dont, to ensure the data is 100% cleanly exported. Hence it may contain passwords or sensative data.
+
+## Exporting SCALE Apps
+
+- Open a Shell, either through SSH or the Web-GUI shell of SCALE
+- cd into the folder you downloaded clustertool into
+- Run now `./clustertool scale export`
+
+This will output a complete dump of the configuration values for your SCALE Apps.
+
+## Converting SCALE Apps to easily readableHelm-Release files
+
+The default json is quite hard to read, to make it easier readable, you can use the SCALE migrate function to generate easier readable files.
+In contrast to the name, this is just a formatting tool and doesn't actually migrate anything itself.
+
+- Open a Shell, either through SSH or the Web-GUI shell of SCALE
+- cd into the folder you downloaded clustertool into
+- Run `./clustertool scale migrate` to convert all exported SCALE Apps to ClusterTool/FluxCD compatible Helm-Releases
+
+This should put a whole lot of "helmrelease.yaml" files, containing the structured App configuration data under "values".
+
+
+## Known Issues
+
+### Some application specific settings might be hidden
+
+Some application specific settings might not directly be created by the user, but instead dynamically generated by us on install.
+Such configuration options will hence, as they are not part of the user-entered configuration, not part of the export either.
+
+### TrueNAS SCALE 24.10 "Electric Eel" not supported
+
+Its **NOT** possible *in any way* to do the migration after updating to TrueNAS SCALE 24.10 "Electric Eel"
