Summary: Download your own files and folders from the old cloud and upload them to the new cloud. Check the data and set up any shares you need again.
Step 0:
If the ownCloud client is installed and in use, please first log out here and then close the client!
Open the old and the new cloud in two browser tabs. That way you can switch between them quickly when needed.
Old cloud (ownCloud): https://zmtcloud.leibniz-zmt.de/
New cloud (Nextcloud): https://cloud.leibniz-zmt.de/
Important: Once you start downloading, stop editing the files in the old cloud. Otherwise you may end up with different versions or missing changes. If other people use your files or folders, agree on the timing with them beforehand. After uploading and checking, everyone works only in the new cloud. If you run into problems or are unsure about any step, feel free to open a ticket.
In the old cloud
Step 1: Review your data.
Decide which files and folders you still need. You don't need to move content under "Shared with you" yourself; the person who owns it is responsible for that. If you need that data, check with them briefly whether it will be moved.
Step 2: Write down your shares.
Under "Shared with others," check who you have shared files and folders with and what permissions apply. Hovering over a file or folder name shows its full path. Also note any public links, along with their password and expiration date if they have them. You will need to set these shares up again later if they are still needed.
Step 3: Download your data.
Select the files and folders and click "Download." You'll then find them on your computer, usually in the "Downloads" folder. If a ZIP file was downloaded, extract it there.
In the new cloud
Step 4: Upload and check your data.
Upload your files and folders via "+ New." Wait until the upload is complete. Check the folder structure and open a few important files.
Step 5: Set up your shares again.
Click the share icon next to the file or folder. Under "Internal shares," add the people or teams, choose the appropriate permissions, and click "Save share." Recreate any public links you need and send them to the recipients. The old links will no longer work after the migration.
Version history, trash, comments, tags, and favorites will not be transferred.
