We migrated from Zabbix 1.8 to 4. As inheritance, several items came in template_linux_servers. I changed the name to Template OS Linux and I want to adjust the items to make it the same, but I don't want to lose the histories. In template_linux_server there are the items [HTTP, FTP, NNTP, SMTP, SSH] server is running, and I want to unlink these items from the template, to delete them later only in the template, keeping them in the hosts. Then I will link the Templates / Modules: Template App [HTTP, SMTP, NNTP, FTP, SSH]. I don't know how this is possible today: unlink an item from the template only.

I can't unlink the whole template because otherwise later, when I link again, I might re-enable all items on the hosts again that have been deactivated.
