Issue Plesk Docker OwnCloud: how to migrate from "devicemapper" to "overlay2"?

[Erwan]

Hi all,

Since 2 years, we have 4 OwnCloud which works with Docker extension on Plesk Onyx.
After a problem with an update, we have found that we must change the storage system from a "devicemapper" to "overlay2".

We found some elements on the web but nothing very precise.
We would like the current owncloud users to have no change. And especially that the procedure is secure without loss of data. Has anyone ever had to do this operation or procedure?
Thank you in advance.

Erwan
