Log into the SQL 2005 server with the Object Explorer. Expand the server to Management > Legacy > Data Transformation Services. Right click on DTS and select the Package Migration Wizard. This should move your DTS packages from the SQL 2000 server to the SQL 2005 server.
Do keep in mind that any ActiveX scripts probably won’t work correctly.
Additionally … some DTS functionality does not convert well. There is a function in SSIS (SqlServer Integration Services) to allow running the package as it was originally defined. Admittedly, this will take a little knowledge of SSIS via Business Intelligence Development Studio (BIDS) … but this is an easy way to start.
Take a look at DTS xChange – product from Brian Knight SS-MVP – for 100 packages may be well worth the small investment as it can really help with the ActiveX tasks. I have no affiliation with Brian or his Company, just want to help… http://www.pragmaticworks.com/dtsconversionoptions.htm
