Greetings.
You can clone a template to another template in the HTML5 GUI as of 3.12c version (not actually sure when the template to template cloning became available).
The only option in the CLI I could find was to generate a service profile from a template.
I also checked the UCS powertools powershell options and that currently seems to also be limited to creating service profile from a template as well.
Thanks,
Kirk...
