Although not recommended you can convert your Legacy 2012 CADWorx Specs

1.  Open up the spec editor and create a new Catalog.

2.  Select the option to import from data table and you can either add each data table or add the folder containing your legacy spec library.  This is most likely your Lib_I folder.

3.  Select the individual data tables you wish to import and select import and match up with type of table they are and import one at a time.

4.  Now create a new Project, and select newly created catalog, then click OK.  In the New PRJ select Import Legacy Specification, Path to legacy spec directory and select each legacy spec to import.
