For example, "centralus" .PARAMETER newLBName Name of the newly created Standard Public Load Balancer. .EXAMPLE ./AzureLBUpgrade.ps1 -oldRgName "test_publicUpgrade_rg" -oldLBName "LBForPublic" -newrgName "test_userInput_rg" -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 Public Load Balancer. #> #> ##User defined paramters #Parameters for specified Basic Load Balancer Param( [Parameter(Mandatory = $True)][string] $oldRgName, [Parameter(Mandatory = $True)][string] $oldLBName, #Parameters for new Standard Load Balancer [Parameter(Mandatory = $True)][string] $newRgName, [Parameter(Mandatory = $True)][string] $newlocation, [Parameter(Mandatory = $True)][string] $newLBName ) #getting current loadbalancer $lb = Get-AzLoadBalancer -ResourceGroupName $oldRgName -Name $oldLBName ##creating froentend ip based on new sku New-AzResourceGroup -Name $newRgName -Location $newlocation ##collaspe #1 and #2 into one loop for each frontend config $newlbFrontendConfigs = $lb.FrontendIpConfigurations $feProcessed = 1 foreach ($frontEndConfig in $newlbFrontendConfigs) { #1. create public IP $newFrontEndIpPublicIpName = ($frontEndConfig.PublicIpAddress.id).Split("/")[8] $newFrontEndIpPublicIpName = "standard$newFrontEndIpPublicIpName" $newFrontEndIpPublicIp = New-AzPublicIpAddress -ResourceGroupName $newRgName -Name $newFrontEndIpPublicIpName -Location $newlocation -AllocationMethod static -SKU Standard $newFrontEndConfigName = $frontEndConfig.Name #2. create frontend config New-Variable -Name "frontEndIpConfig$feProcessed" -Value (New-AzLoadBalancerFrontendIpConfig -Name $newFrontEndConfigName -PublicIpAddress $newFrontEndIpPublicIp) $feProcessed++ } $rulesFrontEndIpConfig = (Get-Variable -Include frontEndIpConfig*) #3. create inbound nat rule configs $newlbNatRules = $lb.InboundNatRules ##looping through NAT Rules $ruleprocessed = 1 foreach ($natRule in $newlbNatRules) { ##need to get correct frontendipconfig $frontEndName = (($natRule.FrontendIPConfiguration).id).Split("/")[10] $frontEndNameConfig = ((Get-Variable -Include frontEndIpConfig* | Where-Object {$_.Value.name -eq $frontEndName})).value New-Variable -Name "nat$ruleprocessed" -Value (New-AzLoadBalancerInboundNatRuleConfig -Name $natRule.name -FrontendIpConfiguration $frontEndNameConfig -Protocol $natRule.Protocol -FrontendPort $natRule.FrontendPort -BackendPort $natRule.BackendPort) $ruleprocessed++ } $rulesNat = (Get-Variable -Include nat* | Where-Object {$_.Name -ne "natRule"}) #4. create LoadBalancer and default outbound rule $newlb = New-AzLoadBalancer -ResourceGroupName $newRgName -Name $newLBName -SKU Standard -Location $newlocation -FrontendIpConfiguration $rulesFrontEndIpConfig.Value -InboundNatRule $rulesNat.Value #-outboundRule $outboundrule #geting LB now after ceation $newlb = (Get-AzLoadBalancer -ResourceGroupName $newRgName -Name $newLBName) #5. create probe config - need to be done LAST!!!
