only after the new backup switch is operational on the network. When you remove the active switch from the
network to replace it, the new backup switch takes over the active switch role. When you add a second switch
to the network, that second switch automatically assumes the role of a backup switch.
This procedure assumes that the existing switches have been upgraded to AOS-W 6.2.x or later. If your switches are
running earlier version of AOS-W, upgrade them to 6.2.x or later before attempting to migrate them to a newer
switch model, such as a OAW-40xx Series or OAW-4x50 Series switch.
Transferring Licenses
To replace a switch with manually added licenses, you will need to transfer those licenses to the new switch as
part of the replacement process.
If the switch being replaced was returned to Alcatel-Lucent as an RMA, the license keys on the RMA switch
cannot be directly transferred to a new device, and must be regenerated. To generate a new license key for a
switch returned as an RMA:
1. Access the My Networking Portal (MNP) at http://hpe.com/networking/mynetworking/.
2. Log in to MNP using the HPE Passport.
3. Click View licenses or Transfer licenses to new platform. All available licenses are displayed.
4. Select the >> icon at the right end of the record to verify the license details before transferring it.
5. Click Transfer License at the bottom of the page.
6. Select a switch from the AOS Controller Type drop-down list.
7. Enter the serial number of the switch in the Serial number text box; or enter the passphrase of the switch
in the PassPhrase text box.
8. Select the license to be transferred.
9. Click Transfer at the bottom of the page. A new license key is generated, which you can apply to the switch.
