We just upgraded to the latest version of SDT. The new version wants to upgrade the existing metadata of my DBC's (which isn't suprising), but I'm a little hesitant to let it until I understand all the implications. We have a bunch of apps. out in the field that use the SDT metadata/classes to upgrade the client's database(s). If I upgrade the metadata to version 6.1, will I need to upgrade/recompile these apps. w/the latest version of SDT (I'd guess "yes"). I'm not planning on using autoinc, if that makes a difference.
