    .SYNOPSIS
    Migrates specified virtual machines IP addesses to IPAM reservations to avoid two IPs to be reserved per server
    .DESCRIPTION
    Finds servers which have two reserved IP addresses,
    removes old NIC and add new NIC with second IP (static IP inside of VM).
    Can be run online but causes small network hickup for servers.
    .PARAMETER vmNames
    List of virtual machine names to be prosessed.
    .EXAMPLE
    Connect-NutanixCluster -Server "prism" -UserName "admin" -AcceptInvalidSSLCerts
    .\MigrateVmIPsToIPAM.ps1 -vmNames "server1","server2"
    #>
