Hey Konstantinos,
Since you are upgrading from an old version, you will need to jump to a middle code (8080f). We have also changed the format of our images in newer codestreams; we now use a UFI image. For you, it would look something like this:
While on 8030h the commands will be:
copy tftp flash
boot
copy tftp flash
Example for 8030h > 8080f (assuming switch code and ICX7250)
copy tftp flash 192.168.1.250 spz10114.bin boot
copy tftp flash 192.168.1.250 SPS08080f.bin primary
wr mem
*reload into 8080f*
Once booted to 8080f:
wr mem (this is necessary to ensure your configuration is upgraded as syntax can change)
copy tftp flash
Example for 8080f > 8092b (assuming switch code and ICX7250 again)
copy tftp flash 192.168.1.250 SPS08092bufi.bin primary
wr mem
*reload into 8092b*
Once you are on 8080f, you can upgrade to any 8090/8092 UFI image.
Let me know if that helps! You can always open a case and we can assist you as well.
