The addition of a new team member involves granting them permission to access shared team resources. This can be done by simply copying all the permissions from any of the team members to the new team member. You can also copy permissions from one user to multiple users.
Similarly, if the new team member is replacing an old team member, all the permissions of the old team member can simply be shifted to the new team member by using the Move Permissions feature.
Navigate to the Management tab.
Under Permission Management, click on Copy or Move Permissions.
Choose the farm/tenant and the sites in which you want to perform the action.
Select the user or group whose permissions you wish to copy in the Source User/Group field.
Select the users or groups to whom the permissions are to be copied in the Destination User/Group field.
If required, include objects with unique permissions or group membership by selecting the respective check-boxes.
Depending on the action you wish to perform, select Copy Permissions or Move Permissions.
Click Apply.
