You will want to migrate the procedures from SQL Server 7 to SQL Server 2000 before migrating them to SQL Server 2005.
I would however recommend migrating them from DTS to SSIS as that will make the packages more upgradable in the future as SQL Server 2008 and up no longer support DTS.
In the packages are fairly simple in nature you can use the DTS upgrade wizard to convert the packages. If they are more complex you’ll need to upgrade them manually.
Thanks but how do you do the DTS upgrade wizard?
