I have swapped out our ZD1100 for a new ZD1200 successfully. I used the backup from the ZD1100 V9.8.3 to configure the 1200. Now I can't get it to recognize the 510 APs as I swap the out. Any ideas? I haven't upgraded ZD yet as I don't want to lose my current AP connectivity until I swap them out.
I am glad to hear that you replaced ZD110 with ZD1200 successfully. ZD1200 started to support R510 from version 9.13. So, pl upgrade the software to 9.13 or above to get it recognized by ZD1200.
It's best to schedule a Change Management period to perform your ZD upgrades, when the least number of users will be affected, that is a best practice.
