I need to convert and preconfigure a lot of IAPs to campus mode and make them to join to a remote controller. After this they will be installed on many sites, every site will contain 1 router and a couple of APs. Every AP will join to the same controller. The routers are preconfigured, and grant L3 connection between the APs and controller through VPN tunnel.
Now the conversion is very slow through VPN, so I wondering about to make it faster.
To make the preconfiguration more fast I wondering about install a small temporary controller on the configuration site with the same IP address and ArubaOS version as the final, and prepare the APs by that. Is it work, if I prepare the APs by the temporary controller, will the APs join to the final controller with the same IP address after install on sites?
I have no access for routers and central controller, only for APs.
Thanks!
