AP Predownload questions

[IT Services]

I have a question in regards using the Efficient AP upgrade feature for Flex Connect.

1) Do you have to predownload to the Flex AP's first before predownloading to the other APs? Or is it possible to setup a Master Flex AP and triggering the predownload (for all APs) will effectively trigger the Flex Connect Efficient AP upgrade function too?

Any insight would be most helpful!

Thanks all!

"When the Efficient Image Upgrade feature is enabled, one access point of each model in the local network first downloads the upgrade image over the WAN link. The process is similar to the master-slave or client-server model. This access point then becomes the master for the remaining access point of the similar model. The remaining access points then download the upgrade image from the master access point using the preimage download feature over the local network, which reduces the WAN latency. "

Normally, when upgrading the image of an AP, you can use the pre-image download feature to reduce the amount of time the AP is unavailable to serve clients. However, it also increases the downtime because the access point cannot serve clients during an upgrade. The Pre-image download feature can be used to reduce this downtime. However, in the case of a branch office set up, the upgrade images are still downloaded to each access point over the WAN link, which has a higher latency. A more efficient way is to use the FlexConnect AP Upgrade feature. When this feature is enabled, one access point of each model in the local network first downloads the upgrade image over the WAN link.The remaining access points then download the upgrade image from the master access point using the pre-image download feature over the local network, which reduces the WAN latency.It works similarly to the master-slave or client-server model
