Hi vaibhavshete, I think the best option to accomplish this task is by CLI, so You can loop on your resources get the OldTag , create NewTag with the value of the OldTag and finally remove the OldTag. An example on powershell could be:

# Get the resource and tags
$resource = Get-AzResource -Name "RESOURCE_NAME" -ResourceGroupName "RESOURCE_GROUP_NAME"
$tags = $resource.Tags

# Check old tag
if ($tags.ContainsKey("OLD_TAG_NAME")) {
    # Store the value of the old tag
    $tagValue = $tags["OLD_TAG_NAME"]
    # Create new tag with old value
    $tags["NEW_TAG_NAME"] = $tagValue
    # Update resource with new tags
    $resource | Set-AzResource -Tag $tags -Force
    # Remove old tag key
    $tags.Remove("OLD_TAG_NAME")
    # Update resource without old tag
    $resource | Set-AzResource -Tag $tags -Force
}

Let me know if this help you. Luis
