If you are regularly creating images so that you have a latest possible copy of a database available, you may want to migrate clones to that new image.

This script will remove existing clone databases for a named image, then create new clone databases in the same location for an updated image.

# 'refresh' all clones to use a newer image
Connect-SqlClone -ServerUrl 'http://sql-clone.example.com:14145'
 
$oldImageName = 'Forex_20170301'
$newImageName = 'Forex_20170302'
 
$oldImage = Get-SqlCloneImage -Name $oldImageName
$newImage = Get-SqlCloneImage -Name $newImageName
 
$oldClones = Get-SqlClone | Where-Object {$_.ParentImageId -eq $oldImage.Id}
 
foreach ($clone in $oldClones)
{
    $thisDestination = Get-SqlCloneSqlServerInstance | Where-Object {$_.Id -eq $clone.LocationId}
 
    Remove-SqlClone $clone | Wait-SqlCloneOperation
 
    "Removed clone ""{0}"" from instance ""{1}"" " -f $clone.Name , $thisDestination.Server + '\' + $thisDestination.Instance;   
 
    $newImage | New-SqlClone -Name $clone.Name -Location $thisDestination  | Wait-SqlCloneOperation
 
    "Added clone ""{0}"" to instance ""{1}"" " -f $clone.Name , $thisDestination.Server + '\' + $thisDestination.Instance;   
}
# Remove the old image
Remove-SqlCloneImage -Image $oldImage;
