How to change digikam collections type?

[Matthieu]

Dear list,

After a new installation of my operating system, I had to reinstall digikam.

In the first launch, digikam asked me if my existing pictures folder was a previous collection? I said yes, but it's a removable device.

Now my collection appear in digilkam as  "collection in a removable device".

I think it could be better to list this collection as "collection in a network share". 

Is there a way to change this collection from "collection in a removable device" to "collection in a network share" without loosing something?

I have database skills if this parameter is stored in the digikam database.

Thanks in advance for your help.

Regards
