Conversion of DTS to SSIS command Line

I am trying to convert a command line using the dtexecui utility. I need to pass three parameters ; account number ,begin and end date to project.

What am i doing wrong ?

DTEXEC /DTS "\File System\Archive Data" /SERVER SRV2 /MAXCONCURRENT " -1 " /CHECKPOINTING OFF /REPORTING EW \package /SET "Account_Number";"'00001'" /SET "File_Name";"'C:\Inetpub\wwwroot\output\Archive\'" /SET "Begin_Date";"'04/03/2006'" /SET "End_Date";"'04/04/2006'"

Error I get

Your command line is not correct as each set command needs a package path starting with \package just as the error message indicates. As I don't know tasks these properties belong to I can't give you the exact path but in general the set option should look something like "\Package.rest_of_path_to_property". You can use the configurations on the package to identify what the package path should look like. You should also remove the \package from the command line outside of the set because that is invalid.

HTH,
