The rsync-migrate script is to migrate from SME.
I’d try to remove the asterisk ghosts first:
- backup your server and
yum remove "*asterisk*" - search for asterisk in the cronjobs and remove if necessary
If it does not work it should be enough to migrate by recovering from a backup.
You could just setup a new server and selectively rsync to it, see Lost users on NethServer v6.10 -> v7.8 upgrade - #6 by Andy_Wismer
