Performing upgrade installation

You can upgrade from versions N_CurVer_Less_1., 2021 and 2020 to Allplan 2023. Earlier versions can only be updated by a previous upgrade at least to version 2020 (with data transfer) and subsequent upgrade to Allplan 2023.

Before starting the upgrade, both Allplan and services application must be closed on all workstations. You cannot work while upgrading. This is only possible again after the upgrade has been completed on all workstations.
