Blaze Advisor upgrade(7.4)

Debraj, it's good news that your project imported/compiled correctly, but you really needed to create a new Repository and that would have created a new Repository Connection in the same step.  Instead, you connected to the Default Repository, which is a simple file-based repository (no versioning) that comes pre-packaged with Blaze.  You should read the Blaze documentation on creating new repositories (doc/pdf/ManagingRepositories.pdf).  After creating your own new repository (and connection), do the import step again and you should now have a new Blaze 7.4 repository with all the old entities imported.  As an alternative, you could probably copy your Default Repository from /Blaze/Advisor74 to another location, rename it, and create a new connection to it.  Your import should have created new folders/projects, so you can probably delete the Default Folder and Default Project.  Your next steps will depend on what you are expected to do with the new repository.  Congrats!
