how to get a list of all clones of an template

[immo]

and visversa the information if a vm is a linked clone or not.
I havent found this in qemu/<vmid>/config.

The reason is if I have to replace the template.... there have no be linked vm anymore.

also some handling proposal for transfering linked clones into full ones without reboot would be good.

linked clones are only linked by their disks, which noted in the disk volume id "storage:base-volume/child-volume"
since on some storages this is not as strict as others (e.g. thinlvm linked clones are not dependant on the base image in contrast to zfs for example)

jut make a full clone of the linked one
