Hi fellow community members,
Yesterday I did an upgrade of a 5508 WLC HA pair with only Flexconnext AP's (mix of 3702 and 1602 AP's) distributed all over Europe. We went from version 8.2.151 to 8.5.135. After the upgrade and before the reboot of WLC's I did an "ap image pre-download". Most of 3702 AP's completed this task, three 3702 AP's failed and all the1602 AP's didn't upgrade (1602 is supported in 8.5.135 following RN).
After reboot most 3702 AP's came up after a while. The three failed 3702 AP's and all the 1602 AP's stayed on status "downloading". After 75 minutes of no status change, we decided to rollback to 8.2.151.
When the WLC's came up with version 8.2.151 the three failed 3702 AP's and all the 1602 AP's were immediately visible and it seemed these AP's didn't suffer any downtime from the upgrade. The uptime of these AP's was more than 80 days so they never rebooted.
My questions are:
1. How can I upgrade the 1602 AP's in a future upgrade plan?
2. The three failed image pre-download 3702 AP's. What's needed to get these working in a future upgrade plan? I've seen this behavior before and then a flash_init via console was needed. That's a bit difficult if the AP's are 2000km far in different places.
Thanks!
Regards,
Thomas
