After ZD2 is successfully upgraded to 9.5, perform the same
upgrade process on ZD1.
13)
ZD1 will restart after the upgrade has completed.
14)
At this point, all APs joined to ZD1 will lose their connection
(heartbeat) to ZD1. APs will then discover ZD2 and AP firmware
will be upgraded to the same version as ZD2. After the APs execute
automatic configuration download from ZD2, APs will join ZD2
successfully.
15)
Verify both ZD1 and ZD2 are upgraded to the same 9.5release. See
step 11 above.
16)
Verify all AP’s have successfully joined to ZD2.
17)
Re-‐configure Smart Redundancy on ZD1 and ZD2.
