Network Programming in .NET

Ok, it’s a common task, you’re migrating from one server to another, but you have one website that responds to 100’s of bindings, and you have to move them. Of course you can copy and paste one by one, but here’s a script to do so. It also works with IDN domains.

First, on the source server, run this;

Import-Module WebAdministration

$siteName = "YOUR_SITE.COM"
$exportPath = "C:\TEMP\bindings.csv"

$bindings = Get-WebBinding -Name $siteName | 
            Where-Object { $_.protocol -eq 'http' } | 
            Select-Object protocol, bindingInformation

$bindings | Export-Csv -Path $exportPath -NoTypeInformation -Encoding UTF8

Then, copy the file bindings.csv to the new server, and import them using this

Import-Module WebAdministration

$siteName = "YOUR_SITE.com"
$importPath = "C:\temp\bindings.csv"

$bindings = Import-Csv -Path $importPath -Encoding UTF8

foreach ($binding in $bindings) {
    $protocol = $binding.protocol
    $bindingInformation = $binding.bindingInformation -split ':'
    $ipAddress = $bindingInformation[0]
    $port = $bindingInformation[1]
    $hostHeader = $bindingInformation[2]

    New-WebBinding -Name $siteName -Protocol $protocol -IPAddress $ipAddress -Port $port -HostHeader $hostHeader
}

This doesn’t work for HTTPS domains, since you need to copy the public/private keys as well, and it’s more complex.
