Firmware upgrade fails with message Aborted, wrong file

[seymour999]

Attempts to upgrade a 3500yl-48G PoE switch (J8683A) using the menu or CLI repeatably fail with the above message.

Old primary is K.12.16, new is K_15_12_0012.swi

Switch has licenses (OSPF, VRRP etc), and I downloaded the licenses version of the new firmware.

Clues welcome.

TIA,

Evan

I think you will need to go through several iterations (and it will say exactly what is required in the readme file!)

Most likely K12 --> K13 --> K14 --> K15

Thanks, Richard - that did work.

Only needed two steps between, but your approach is correct.
