Moving Public Folder AddressList from Exchange 2003 to 2010 abd get error

Hi everyone

I'm about to move services from Exchange 2003 to Exchange 2010. When I run the command "Set-AddressList "Public Folder" -RecipientFilter {RecipientType -eq "PublicFolder"}" I got the error below:

Invoke-Command : Cannot bind parameter 'RecipientFilter' to the target. Exception setting "RecipientFilter": """ is not a valid operator. For a list of supported operators see the command help.
"RecipientType -eq "PublicFolder"" at position 15."
At :\Users\administrator.<domain>\AppData\Roaming\Microsoft\Exchange\RemotePowerShell\<mailserver>\<mailserver>.psm1:42613 char:29+   $scriptCmd = { & <<<<  $script:InvokeCommand `
    + CategoryInfo          : WriteError: (:) [Set-AddressList], ParameterBindingException
    + FullyQualifiedErrorId : ParameterBindingFailed,Microsoft.Exchange.Management.SystemConfigurationTasks.SetAddress
List"  Clues? All replication works.
