OD-DD Sync with a batch

System

Currently, I'm attempting to run an OD-DD sync and when I run datadeploy - I'm trying to fire off a batch file and was wondering the best-practice for doing so - right now my DNR part fails because I'm trying to run a *.bat instead of *.ipl

<deployNRun >
<dnrDeployment location="source" when="before" state="success" >
<script cmd="d:\iw-home\interwoven\teamsite\iw-perl\bin\iwperl.exe d:\iw-home\interwoven\DataDeploy\bin\ddsync.ipl c:\tmp\predeploy dumpdir dump full /default/main/test/WORKAREA/integration" as="" where="d:\iw-home\interwoven\OpenDeploy\OpenDeployNG\conf" async="no" >
</script>
</dnrDeployment>
<dnrDeployment location="target" when="after" state="success" >
<script cmd="d:\iw-home\interwoven\DataDeploy\bin\db.bat c:\tmp\production dumpdir loaduds full c:\tmp\production\targdir" as="" where="d:\iw-home\interwoven\OpenDeploy\OpenDeployNG\conf" async="no" >
</script>
</dnrDeployment>
</deployNRun>
