Duplicating security groups
If you need to create a security group that is similar to an existing one, you can save time by duplicating and editing an existing group.
1. Choose View > Security Groups.
2. Select a group and click Duplicate.
The duplicated security group is created using the name of the existing group with .1 appended to the name. For example, if the existing group is named Development, the duplicated group is named Development.1.
3. Modify the duplicated security group and save the changes.
