Powershell meets TM1 again: List all the TM1 objects that exist on one server but not on the another

Now that I’ve fallen in love with Powershell I made effort to have yet another useful (?) script to use along with TM1 model deployments. When you are deep in the development phase of your project you end up adding and deleting objects all the time. At the same time when you use file-based deployment (copy datafiles from server to another) you might end up in situation where your target server has old objects that don’t exist in the source anymore (they’ve been deleted or renamed).

There is no fast built-in feature to check which objects in target environment (production?) doesn’t exist in the source (development?) no more. Here is a piece of Powershell script that gives you a list of all the TM1 objects that exist on one server but not on the another

$datafilesfolderA = ""
$datafilesfolderB = ""

Compare-Object (gci $datafilesfolderA | Where-Object {$_.Name -like "*.pro" -OR $_.Name -like "*.cho" -OR $_.Name -like "*.cub" -OR $_.Name -like "*.dim" -OR $_.Name -like "*.rux"} | Where-Object {$_.Name -notmatch "}"} | Select-Object name) (gci $datafilesfolderB | Where-Object {$_.Name -like "*.pro" -OR $_.Name -like "*.cho" -OR $_.Name -like "*.cub" -OR $_.Name -like "*.dim" -OR $_.Name -like "*.rux"} | Where-Object {$_.Name -notmatch "}"} | Select-Object name) -Property Name
