Copying form library with content and workflows attached?

I have used this to export and import an infopath library

 #Loop through the lists, export the list from the source, and import the list into the destination  
  foreach($list in $lists)  
  {  
  "Exporting " + $sourceWebUrl + $list 
   export-spweb $sourceWebUrl -ItemUrl ($list) -IncludeUserSecurity -IncludeVersions All -path ($path + $list + ".cmp") -nologfile
      "Exporting complete." 
   "Importing " + $destWebUrl + $list  
   import-spweb $destWebUrl -IncludeUserSecurity -path ($path + $list + ".cmp") -nologfile  
   "Importing Complete"  
   "`r`n`r`n"  
 }
 

however it did not copy my workflows with the content? How do I do that? Also, I get this message when viewing forms.
