WhatsUp Gold 2017 supports direct upgrade installations from WhatsUp Gold v15.x, or v16.x.
Important: In an effort to make WhatsUp Gold more compliant with more advanced IIS environments during upgrade, you will be prompted for your Windows account password. Please enter the Windows account password created during initial WhatsUp Gold installation to proceed. Or, if you do not know the password for this account, you can enter a new one at this point. When prompted by WhatsUp Gold, please confirm you understand the password entered is new and will replace the password for the original Windows account.
Important: WhatsUp Gold 2017 Plus Distributed edition uses an updated communication channel and is not backwards compatible with earlier versions of WhatsUp Gold. This means WhatsUp Gold 2017 Distributed installations can not communicate with previous versions of Distributed edition. If systems are updated individually, they will be unable to communicate with legacy systems until they are upgraded to WhatsUp Gold 2017 Plus. Note that systems continue to function and collect data regardless of version, though once upgraded to WhatsUp Gold 2017 Plus, the Central/Remote communication connection will be reestablished.
For additional information regarding upgrading the application from a previous version, please see the WhatsUp Gold Release Notes.
