How do I move from Classic to NG ?

Here's a doc you definitely want:

http://docs.aerohive.com/330000/docs/guides/Aerohive_HiveManagerNG-Migration.pdf?_ga=2.234056670.1329224720.1526344440-454282283.1511914886

As someone currently migrating devices from Classic to NG, here's some "big picture" items - a 10,000 foot view - let's call this Things I Wish I'd Understood Better Beforehand:

Apparently, you can just go into to Classic's license key management interface, list all the keys you have in Classic, and go apply those same keys into NG; I copied my licenses into NG in about 30 seconds this way without involving support.
You're basically just going to pretend like you're building your network from the ground up again, but in NG (so you're gonna want to go figure that out), then migrate the devices from Classic to NG one or more at a time.
The summarized process of actually 'moving' a device to another HiveManager goes like this:
1. Establish an SSH connection to the device + write down the IP address and HiveManager password to connect to it - this isn't required but you will kick yourself later when you mess up and you can't remember the device IP and it's not in HM because you just deleted it
2. Write down the device serial number
3. Change the CAPWAP redirector to redirector.aerohive.com, either via CLI (make sure to save changes) or via HiveManager+config push
4. Once the configuration is committed to the device, schedule a reboot of the device for several minutes in the future, giving you time to do the next few steps BEFORE IT REBOOTS (<--- this part is important):
  1. Remove the device from HiveManager Classic by deleting it from the inventory
  2. Add the device to HiveManager NG using the serial number + network policy
  3. The device will boot up, contact redirector.aerohive.com, and be told to connect to HiveManager NG

Tips:

Create a device template for each type of device you have, before you get started. For example, the switch templates for my SR2324 and SR2348 switches specifies that the 4 10G ports have trunking enabled, STP is enabled, on all ports, and ports 1-24 (or 48) are end-user ports.
application stop hiveagent + application start hiveagent are CLI commands (for Nimitz-based devices such as the SR23xx switches) that can restart the hivemanager agent running on the device - after being disconnected from the 'net for a few days, our HM agent gave up trying, and this reconnected it to the hive without restarting the switch.

For a clearer understanding of all the 'redirector' business, check out the last 2 pages of the PDF I linked above, it explains the various ways that Aerohive devices can locate their HiveManager;

He will need device inventory permissions (needed both for export and for removing devices from the hive) in order to remove the devices from the hive so they can be added to his new NG hivemanager, so your best route right now is to get super user priveliges or you are going to be dead in the water during the migration anyway.

If you don't see the device inventory that usually means you aren't logged in as the super user (a good way to check is to see if you can enter entitlement keys, if you can, you are a super admin).

Another work around would be to do a configuration export from classic and import it in to HiveManager (formerly NG), this will bring your device inventory and maps over for you in to NG.

Well that's confidence inspiring in the platform. I have touched aerohive periodically, so don't not the granular differences like this, but seems I'm running an out of date or irregular version of even the old hivemanager - not sure how that happens in a cloud managed environment.

I'd really like to just move on, but seems we'll have to do this the hard way of importing the ap's and renaming them.

I have no idea why yours doesn' t have the button, here's my old hivemanager

2. I would suggest using the Copytables extension for Chrome to copy the table data instead, but that doesn't get you much further..... missing the Device Inventory button means you also don't have a "remove" option to remove the devices from inventory, so you need to get this fixed before you can proceed

This was good info, and working on this for a customer, but I'm finding my old hivemanager instance is missing the device inventory button to export the CSV of the AP details from the directions, and can't seem to find anything comparable. Any thoughts where to produce the export of the devices from now?
