Hi,
I am trying to add a user with all system administrator permission, as I am the system administrator, he also should be able to perform all the activities.
He need ALL DELETE ACCESS (projects/users/issues...everything).
I tried updating global permission but there is not such permission setting to assign system-administrator to a group

For now I have made the user the organization admin - but need to understand if there can be more than one system-administrator?
If not then how to transfer the permission to another user?
Please help.
