I have done this before when moving log file locations in Exchange and it’s well cool and make life very easy!

NTFS access permissions can be complex and tricky. To quickly assign NTFS permissions to a new folder, you can simply clone permissions from another folder that you know has the correct permissions applied.
md $homesample
# manually assign correct permissions to folder “sample”
$sddl = (Get-Acl $homesample).Sddl
md $homenewfolder
$sd = Get-Acl $homenewfolder
$sd.SetSecurityDescriptorSddlForm($sddl)
$sd.Sddl
Set-Acl $homenewfolder $sd
Unfortunately, setting ACLs this way always requires administrator privileges.
