Upgraded a server last night which took about 4 hours. For a long time, my interactive job was in a SVFW status with 0% processor. I took a look via WRKSYSACT and noticed a task called LDFX02 running there and just eating up the processor. Of course, the setup wizard via Windows tells you it will happen, but gives no time estimate based on your current configuration. However, I did the install using RSTLICPGM and after a while of waiting I remembered that the program conversions would occur during the upgrade.
