Migration to "devicemapper" to "overlay2"?

Hello all,

We use 4 Owncloud on a Centos Plesk with docker extension.
We must change ther storage from “devicemapper” to “overlay2” and we don’t know how to make it and most importantly in a secure way without losing data and if possible without there being any change for the users Owncloud.

Do you know how to made it securely?

Thanks a lot.



this looks to me completely unrelated to ownCloud. I think you should ask questions about Docker and how to work with docker in https://forums.docker.com/ where you can find way more experienced users with Docker then in a forums of the software running within your Docker environment. :slightly_smiling_face:

As Docker is a widely used software and you’re probably not the first one who needs to migrate the docker storage engine on a live environment a search on e.g. google might even lead you to what you’re looking for.
