Migrating Libraries to ARCHICAD 20

IMPORTANT: When migrating an older-version project, if you want to use the newest library, make sure you use the Migrate ARCHICAD Libraries function. If you add and delete Libraries using Library Manager, you may end up with a large number of missing library parts.
Note: The automatic Migration process described below is available only for projects that use ARCHICAD Libraries 10 and later.
Click Migrate ARCHICAD Libraries. This process will do the following:
If instead you choose Skip Migration, you will load the old Library that was saved with the project. All placed objects will be available from that library, but you will not be able to use any library improvements and fixes from the latest version.
Use the Migrate ARCHICAD Libraries button in Library Manager.
Note: If the button is not shown in Library Manager, this is because ARCHICAD has determined that there is no need for it: all needed libraries (latest ARCHICAD library plus Migration libraries) have already been loaded; and the project has no missing library parts.
During this process, make sure that the Migrate ARCHICAD Libraries checkbox is checked. This will ensure smooth migration of your ARCHICAD Libraries together with the Teamwork project.
Note: Some objects in your migrated Teamwork project may be listed as “Temporarily Missing” in the Library Manager or in the Library Loading Report. As soon as other users do a Send and Receive, this problem will be solved automatically.
If you still want to edit this library with older-version projects (e.g. AC 18 or AC19), it is best to click Cancel here, and use the older-version ARCHICAD to reserve and edit the library and its contents.
ARCHICAD Migration Libraries serve this purpose: they contain only those objects from an earlier-version ARCHICAD Library that do not have counterparts in the latest-version ARCHICAD Library. A Migration Library is much smaller than full-version ARCHICAD Library.
Migrate ARCHICAD Libraries: This function, used when opening an older-version project in ARCHICAD 20. Migration Libraries are loaded automatically.
Consolidate: If you have placed objects from multiple ARCHICAD libraries and have loaded all the libraries, you will be prompted to Consolidate your libraries. As part of the consolidation process, Migration Libraries are loaded automatically.
If you do not use these workflows which load the needed Migration Libraries, then some of your placed objects from older-version projects may not have a compatible corresponding object in ARCHICAD 20. In this case:
Note: Available migration libraries may vary, depending on your localized version.
Note the additional Library-related changes when migrating projects from ARCHICAD 12 and earlier:
If you use the Migrate Libraries or Consolidate functions as described above, the Migration Libraries will be loaded automatically, together with the necessary obsolete objects, and you won’t have any missing objects.
Note: You will only be able to access only those obsolete objects from the Migration Libraries that have already been placed in your project.
To expedite this, use Parameter Transfer: this way, you will pick up the old window’s parameters and inject them into the new window before placing it. This still won’t produce an exact replica, but everything that can be replicated will be, and this will save you manual work.
Click OK to close Window Settings and to replace the old window with the new one, using the changed parameters.
