the easiest way to transfer DTS packages is with bcp, not only works with 2000 but also will move to 2005 as well.
EXEC master.dbo.xp_cmdshell "bcp msdb.dbo.sysdtspackages out f:\DRTEST\DTS_Packages.txt -c"
EXEC master.dbo.xp_cmdshell "bcp msdb.dbo.sysdtspackages in f:\DRTest\DTS_Packages.txt -c -E -T"
DBAs often ask how to transfer DTS packages and move them between servers. They also want a version control system that is more robust than that provided in msdb. Steve Jones looks at one of the features of the DTS designer that solves both of these problems.
