From "USCIS Online Change of Address" below, it seems we can do change of address online and no need to file AR-11 and call USCIS Service Center. Is that correct?
Thanks in advance for clarification.

USCIS Online Change of Address
Introduction
Customers who have an application and/or petition which has been filed with USCIS but has not yet been decided (also known as a 'pending' case) should notify USCIS of any change of address as soon as possible after moving.
The law requires nearly all non-U.S. Citizens1 to report a change of address within 10 days of moving by completing a Form AR-11. Abiding by these legal requirements and completing the necessary forms does not update an address on any applications or petitions pending with USCIS. Non-citizens with pending cases must do both.
Most customers can now notify USCIS to change their address on a pending case online here on our website. Non-citizens can also now complete the Form AR-11 online here on our website.
If you choose to change your address online using our Online Change of Address Notification tool, you will need to have some information available. Please have the following information available before you begin:
Your receipt notice or other notice we sent you showing your receipt number (if you have a pending case with USCIS).
Your new address
Your old address
If you have filed a petition for a family member, please have the names and biographical information for that person.
When you last entered the United States (if you cannot remember this information please fill in an approximate date)
Where you last entered the United States (through what port of entry you entered - whether by land, sea or air)
