Connector Group Region
When you create a connector group, choose a Secure Access region that is as close as possible to the location where the private resources that will be associated with the group reside.
Choose the region for your connector groups carefully. You cannot change the region associated with a connector group.
If you need to change the region, you must create a new connector group associated with the new region. Then, deploy connectors in that group and delete the original connector group and its connectors.
