Option-2
Normally I do, to install new omnivista with same software version as the old and Same IP address.
Get the configuration backup from OLD omnivista (using CLI & SFTP) and restore the configuration in the new.
You can transfer/re-use the Licenses which should not create any issues
Now if you want to change the IP address of New Omnivista , you can do it.
Later you can move the APs from OLD OV to New Omni vista. Please screenshot attached.
Could you please advise whether we can transfer the old Device and HA license while creating the new OV2500 NMS server in VM and provide the steps to take those old licenses.
you can login into OV2500 using SSH , Select the options Configure The Virtual Appliance --> Display Current Configuration - you will see the license keys
