For example, "centralus" .PARAMETER newLBName Name of the newly created Standard Internal Load Balancer. .EXAMPLE ./AzureILBUpgrade.ps1 -rgName "test_InternalUpgrade_rg" -oldLBName "LBForInternal" -newlocation "centralus" -newLbName "LBForUpgrade" .LINK https://aka.ms/upgradeloadbalancerdoc https://docs.microsoft.com/en-us/azure/load-balancer/load-balancer-overview/ .NOTES Note - all paramemters are required in order to successfully create a Standard Internal Load Balancer. #> Param( [Parameter(Mandatory = $True)][string] $rgName, [Parameter(Mandatory = $True)][string] $oldLBName, #Parameters for new Standard Load Balancer [Parameter(Mandatory = $True)][string] $newlocation, [Parameter(Mandatory = $True)][string] $newLBName ) #getting current loadbalancer $lb = Get-AzLoadBalancer -ResourceGroupName $rgName -Name $oldLbName #1.
