We are in the process of migrating from Cisco to Aruba on campus as well. In order to facilitate a smoother transition, we set up a different ssid (actually 3, one for.1x, one guest, and one IOT (Mac based with MPSK)).
The vlans are different, ip ranges are new (and larger to accommodate more devices), and there are many more APs. That allowed us to leave the Cisco stuff alone - it still works, and the user can still connect, but we plastered signs about the campus advising everyone of the new networks.
Since the process is different, it allows us to train users without denying access to those with existing devices. They can take a few weeks to cut over devices and our help desk isn't over burdened with students moving in with connecting issues.
Through the semester we will begin to remove the old Cisco devices, which will force those still on the old to switch, but at a moderate pace.
It also lets us refine the process, instructions, etc with less pressure to make sure all the bugs are worked out. If it's busted, they can connect to old-network until we can figure out their issue to get them on new-network.
hth
good luck!

Thanks for your reply, I'm curious about what kind of issues you encountered especially when both networks are advertising the same SSID at the same location:
- Roaming issues
- Did you assigned new IP addresses to the clients or used the same IP space as before?
- Any issues with sticky clients "to Cisco AP" in a BYOD environment?
- ANy DHCP issue caused by the same client requesting addresses on different networks?
In my case, I can only migrate per floor (Client can see the same SSID advertised by Aruba and Cisco). No low activity period.

When we migrated out University yeas ago, we first migrated the residences that were geographically separated from the campus classroom buildings during a break between semesters.
We then tried to migrate other areas during low usage times, usually overnight, to try an minimize coverage overlap of the two systems.

Do you have any other tips regarding the migration from Cisco to Aruba?
Anyone has a document with migration best practices.
Thanks in advance

Interesting find. I found that when I went from WPA3 auth to WPA2 auth, it seemed to fix all my slowness issues. Anyone else see these kind of issues when using WPA2 or WPA3?
