Yes, you can. Ideally you would just leave the APs connected and upgrade/downgrade the ZD, which would then automatically upgrade/downgrade the APs' firmware to match the ZD build.
But you seem to be in a more complicated spot (ZD on 9.8 won't be able to talk to APs running 10.1). So yes, I suggest doing the AP downgrades using a laptop connected directly to the AP.
Here's what I would do:
1. If ZD is already on 9.8, leave it there, and check to make sure it can control your 7363s.
2. Once the ZD and 7363s are working properly on 9.8, downgrade your 7372s to Standalone (Solo) AP firmware 100.1 or earlier - you could also use Solo AP firmware 9.8.2 (see
https://support.ruckuswireless.com/products/42-zoneflex-7372#firmwares).
3. Connect the 7372s to the ZD network and allow them to join. They should automatically up/downgrade to ZD 9.8 firmware this time.
Hope it helps!
