Script to remove DNS suffix for source domain.

 We are migrating from source to target domain and  need to get rid of source domain suffix if it is listed under "Append these suffixes in order" and add the suffix for the target domain instead. Is there a script that can remove suffix for the old source domain and add the new domain suffix?

THank you very much.

Refer to link below, this way you could set the suffix to what you want using PowerShell:
Try this; note that the script needs to be run elevated:
$OldSuffix = ""
$NewSuffix = ""
$Nics = Get-WmiObject -Namespace "Root\CIMv2" -Query "Select * From Win32_NetworkAdapterConfiguration Where IPEnabled='True'"
$DNSDomainSuffixSearchOrder = @()
ForEach ($Nic In $Nics) {
	If ($Nic.DNSDomainSuffixSearchOrder -contains $OldSuffix) {
		$DNSDomainSuffixSearchOrder = $Nic.DNSDomainSuffixSearchOrder -replace $OldSuffix, $NewSuffix
If ($DNSDomainSuffixSearchOrder.Count -gt 0) {
	"Setting new DNS Suffix Search Order: $($DNSDomainSuffixSearchOrder -join ',') ..."
	$Result = ([wmiclass]"Win32_NetworkAdapterConfiguration").SetDNSSuffixSearchOrder($DNSDomainSuffixSearchOrder)
	If ($Result.ReturnValue -eq 0) {
		"... OK."
	} Else {
		"Error '$($Result.ReturnValue)' when setting the new DNS suffix search order!" | Write-Error
} Else {
	"DNS Suffix '$($OldSuffix)' not found."
