how to use powershell object properties directly without typecasting and spliting?

I have created a small script to transfer value of Active directory pc attribute called pssfulllocation from one pc to anoter pc..

To achieve this I have to use typecasting + splitting..

Here is the script which works

$oldpc=read-host "Enter old pc name"
$newpc=read-host "Enter new pc name"
$my=Get-ADComputer -Identity $oldpc -Properties * | select pssfulllocation 

  $itemcast=[string]$my
  $b = $itemcast.Split("=")[1]    
  $c=$b.Split("}")[0]

Set-ADComputer -identity $newpc -Replace @{pSSFullLocation="$c"}

and the output will nicely do the intended job.. in this manner.. and this is the desired result..

But if i don't use typecasting + splitting as per the below script--

$oldpc=read-host "Enter old pc name"
$newpc=read-host "Enter new pc name"
$my=Get-ADComputer -Identity $oldpc -Properties * | select pssfulllocation 
Set-ADComputer -identity $newpc -Replace @{pSSFullLocation="$my"}

the out put is below.. which is not what i want..

In a nutshell if i don't use typecasting + splitting output will be added as @{pSSFullLocation=C/BRU/B/0/ADM/1 but it should only be added as C/BRU/B/0/ADM/1 as per this:

I feel typecasting + splitting should be a workaround and not the proper method.. Any other powershell way to achieve this without using typecasting + splitting ?

Don't do this:

$my=Get-ADComputer -Identity $oldpc -Properties * | select pssfulllocation 

You don't Select-Object to access an attribute's value. Note the -Object, not -Attribute, in the cmdlet name. Instead, collect the object returned by Get-AdComputer then use the attribute directly.

$my = Get-ADComputer -Identity $oldpc -Properties *
$psfl = $my.pSSFullLocation
Set-ADComputer -identity $newpc -Replace @{pSSFullLocation="$psfl"}

Or even this could do the job "-expandproperty"

$oldpc=read-host "Enter old pc name"
$newpc=read-host "Enter new pc name"

$my=Get-ADComputer -Identity $oldpc -Properties * | select -expandproperty pssfulllocation 

Set-ADComputer -identity $newpc -Replace @{pSSFullLocation="$my"}
