HI hope someone can help i am in a little pickle, i am trying to import/insert a Orion map with Powerhsell i have the below:

Add-PSSnapin swissnapin


#connect to poller with username used to log on to SW
$swis = Connect-Swis -Hostname xx -UserName xx -Password xx
$path = "newname"
$imagefile = [system.IO.File]::ReadAllBytes('C:\SolarWinds\somthing.orionmap')
$owner = "xx"
$filetype = "0"
$timestamp = Get-Date
Invoke-SwisVerb $swis Orion.MapStudioFiles insertfile @($path,$imagefile,$owner,$filetype,$timestamp)
