# Cloud Data Migration

Cloud data migration refers to the process of moving files between different cloud storage services. Within the Universität Greifswald infrastructure, this typically involves moving data from the [[groupware]] file module to [[nextcloud]].

## Migration Requirements
Because there is no direct server-to-server migration tool provided for these services, the migration must be performed via a local intermediary computer. The computer must have:
- A stable network connection.
- Valid access credentials for both the source and destination services.

## Migration Scenarios

### Scenario 1: WebDAV-based Migration
This method is preferred for users who want to move files within their operating system's file explorer.
1. Establish a WebDAV connection to the source service (e.g., Groupware).
2. Open the destination service (Nextcloud) either via a web browser or through the installed [[nextcloud]] client.
3. Copy and paste the files from the WebDAV directory to the Nextcloud destination.

### Scenario 2: Archive-based Migration
This method is suitable for bulk downloads of directories.
1. In the source service (e.g., Groupware), select the desired folder/files and choose "Download selected."
2. Download the resulting ZIP archive to the local computer.
3. Extract the ZIP archive.
4. Upload the extracted files to Nextcloud via the browser or the [[nextcloud]] client.
