As with all new versions, the topic of migrating specs comes up. In my experience, I’ve run into two little tricks that clarify the process of migrating content to a new version.
When you migrate specs, the spec editor is not modifying the spec or catalog that you select, it makes a copy. The modified catalog is stored in a Migrated Content folder in your Shared Content Location:
The other part of migrating catalogs has to do with migrating block-based parts. When you reference a block in a catalog, Plant 3D stores a copy of it in your Shared Content folder in a folder that matches your catalog name. The default path for a catalog called ECAD Houston would be something like: C:\AutoCAD Plant 3D 2013 Content\CatalogSupportFolders\ECAD Houston\.
If you look in that folder, you will see folders like 200 and DWG. The 200 folder stores images of the block you created, and the DWG stores a source file for the catalog to use.
When you migrate your catalog, even though the program asks for the content location, it doesn’t use it or migrate it. To finish the migration process, you have to manually move the content to your new shared content folder.
So, I copied the folder C:\AutoCAD Plant 3D 2013 Content\CatalogSupportFolders\ECAD Houston\, to C:\AutoCAD Plant 3D 2014 Content\CatalogSupportFolders\ECAD Houston\. From that point on, my specs, catalogs, and models could find the information required.
Launch the Migration function.
Click Migrate, noting that the files are going to be moved to the Migrated Content folder.
Select your specs/catalogs. I typically move the catalogs first, and then the specs.
Specify the content folder. For moving from 2013, I chose C:\AutoCAD Plant 3D 2013 Content\ even though that appears to have no effect.
The catalog is migrated, you can move it out of here if necessary.
Copy the supporting files and folders for block-based content.
