The Migrate ARCHICAD Libraries process may take several minutes.

When you open an older-version project in ARCHICAD 21, and if your project includes an ARCHICAD Library (version 10 and later), you are prompted to use the Migrate ARCHICAD Libraries function:Ĭlick Migrate ARCHICAD Libraries. Migrate ARCHICAD Libraries when Opening Older-Version Project Note: The automatic Migration process described below is available only for projects that use ARCHICAD Libraries 10 and later. If you add and delete Libraries using Library Manager, you may end up with a large number of missing library parts. IMPORTANT: When migrating an older-version project, if you want to use the newest library, make sure you use the Migrate ARCHICAD Libraries function. We recommend that when you migrate a project to ARCHICAD 21, you also migrate your older-version Library to the ARCHICAD 21 Library, using the easy and automatic Migrate ARCHICAD Libraries function. However, if you stay with your older libraries, you will not get the full benefit of library improvements and fixes in ARCHICAD 21.

The new version of ARCHICAD will work perfectly well with any older-version ARCHICAD libraries.
