DocSafe and myCloud cannot currently be merged (automatically). These are two independent products with different target groups,
which are operated separately from each other and managed by different Swisscom divisions.
Providers who automatically transfer documents to their DocSafe account have no connection to myCloud.
If you want to transfer documents stored in your myCloud to Docsafe, they must be downloaded locally and uploaded again (or vice versa).
Conversely, images can be stored in DocSafe, for example, but DocSafe offers considerably fewer functions such as myCloud, for example viewing images on TV, or editing images.
In this respect, it depends on your needs and requirements which of the two services you want to use (or both).
