Library switch is a feature which makes it easy to switch processes between secondary data libraries. This was created to make upgrading to a newer library version easy, although it is also possible to ‘downgrade’ to an earlier library version.
One benefit of having a library switch is that if you do long time projects or have old projects it is easy to update it to the newest data. For example, you want to switch to a new library such as ecoinvent 3.11 or compare results to an older library such as ecoinvent 3.8, then you can use this feature.
Please note! Only libraries with the same product libraries can be switched in projects (e.g. ecoinvent libraries). Keep in mind that switching between libraries with different calculation methods (such as from ecoinvent 3.11 Cut-off to ecoinvent 3.11 Consequential) is not possible at the moment.
