Hi @V V Satyanaray1 
If your service account has all the necessary access to modify the user OU in AD, then you can run the below custom powershell cmdlet on yiur mid server.

# Replace with the user's distinguished name (DN)
$userDN = "CN=JohnDoe,OU=OldOU,DC=example,DC=com"

# Replace with the target OU where the user should be moved
$targetOU = "OU=NewOU,DC=example,DC=com"

# Move the user to the new OU
Move-ADObject -Identity $userDN -TargetPath $targetOU

# (Optional) Verify the move by getting the user's new OU
Get-ADUser -Identity $userDN | Select-Object DistinguishedName, Name, ObjectClass

Regards,
Siva
