Juniper ex4200 virtual chassis software upgrade

I have 4 EX4200 configured with virtual chassis. I need to upgrade the firmware. I have never done an upgrade with Juniper with virtual chassis. Do I upgrade one switch at a time or I just initiate the command and it will upgrade for all the switches? Thanks

First you need to back up your configs!!!

The EX-Series Switch Virtual Chassis (VC) software can be upgraded for the entire VC or you can upgrade one individual member of the VC.

EX-Series Switches in a virtual chassis environment can be upgraded individually or all members at once from the Master EX (Routing Engine (RE)).  This procedure defines how to use either method.

To upgrade all members, use the command 'request system software add <file> reboot' on the master chassis (RE).  This command will upload the software file to all Virtual Chassis (VC) members and reboot them when the upload is complete.

To upgrade one member of a VC use the command 'request system software  add <file> member <member_number>' on the master chassis (RE).  This will upload the file to the requested member chassis only.

To find the member id use the command:

    user@switch> show virtual-chassis status
    Virtual Chassis ID: 001f.1230.478                                        Mastership              Neighbor     List
    Member ID       Status    Serial No        Model            priority       Role      ID     Interface
    0 (FPC 0)       Prsnt     BN0000000001     ex4200-24p         255          Master*     1      vcp-0     2       vcp-1
    1 (FPC 1)       Prsnt     BQ0000000002     ex4200-48p         254          Backup      2      vcp-0     0       vcp-1
    2 (FPC 2)       Prsnt     BM0000000003     ex4200-24t         128          Linecard    0      vcp-0     1       vcp-1
