Dropbox: directly from Rclone to Duplicacy

I have a folder that is already backed up to Dropbox with Rclone. I would like to start backing up this folder with Duplicacy (in Dropbox also), and to do this transition without having to redo the entire upload.

After doing the initial server side backup I would continue to make regular backups from the original local folder using Duplicacy.

I’m trying to figure out a way to make an initial backup of the Rclone-generated folder to the new Duplicacy folder, using Duplicacy backup or copy without downloading and reuploading the files.

I was unable to view any form. Any ideas? It’s possible?

That is not possible. The best you can do is to find a computer with a faster connection, download the original Dropbox folder to there, and then run the backup command to upload it to Dropbox in the Duplicacy format.
