Reg Upgrading LTM from 9.4.2 to 11.2

i think you have to upgrade to version 10 first. You can't jump to v 11 from version 9.

just in case you have not seen this.

sol13845: Overview of the supported BIG-IP upgrade paths and upgrade planning reference

hope this helps.

If you have access to the support site, there's several documents there for upgrading active/standby systems. They go into great detail on the migration path from 9.x to 10.0, and then onto 10.1 and beyond.

I tried with clean installation, and followed the below steps

1) Downloaded 11.2 iso file and burned on DVD 2) Connected an USB DVD ROM to F5 and inserted burned DVD 3) Rebooted the box, and started for installation 4) I got below message and installation strucked in mid Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key

any idea on this.

just wondering if the installation has been started (i.e. is disc usable?).

yes image is burned on the disc and usable. any options to select boot option variables.

i understand disc is bootable. by the way, how did you burn the disc?

with ISO Burner on 4x speed. Do you find any issue on writing the DVD ?

I upgraded the box successfully to 11.2.0.
