	As with all experimental physics facilities, NIF has software applications that must persist on a multi-decade timescale. They must be kept up to date for viability, sustainability and security. We present the steps and challenges involved in a major application upgrade project from Oracle APEX v5 to Oracle APEX v19.2. This upgrade involved jumping over 2 major versions and a total of 5 releases of Oracle APEX. Some applications that depended on now legacy Oracle APEX constructs required redesigning, while others that broke due to custom JavaScript needed to be updated for compatibility. This upgrade project, undertaken by the NIF Shot Data Systems team at LLNL, involved reverse-engineering functional requirements for applications that were then redesigned using the latest APEX out-of-the-box functionality, as well as identifying changes made in the new Oracle APEX built-in ’plumbing’ to update custom-built features for compatibility with the new Oracle APEX version. As NIF enters into its second decade of operations, this upgrade allows these aging applications to function in a more sustainable way, while enhancing user experience with a modernized GUI for Oracle APEX web-pages.

As with all experimental physics facilities, NIF has software applications that must persist on a multi-decade timescale. They must be kept up to date for viability, sustainability and security. We present the steps and challenges involved in a major application upgrade project from Oracle APEX v5 to Oracle APEX v19.2. This upgrade involved jumping over 2 major versions and a total of 5 releases of Oracle APEX. Some applications that depended on now legacy Oracle APEX constructs required redesigning, while others that broke due to custom JavaScript needed to be updated for compatibility. This upgrade project, undertaken by the NIF Shot Data Systems team at LLNL, involved reverse-engineering functional requirements for applications that were then redesigned using the latest APEX out-of-the-box functionality, as well as identifying changes made in the new Oracle APEX built-in ’plumbing’ to update custom-built features for compatibility with the new Oracle APEX version. As NIF enters into its second decade of operations, this upgrade allows these aging applications to function in a more sustainable way, while enhancing user experience with a modernized GUI for Oracle APEX web-pages.
