firmware update
Firmware of our usg40 is 4.11. I'd like to upgrade firmware to 4.35.
I found following recommendation in old release note.
Recommended upgrade to ZLD4.32 C0 or later version first before upgrading
to ZLD ZLD4.35.
Recommended upgrade to ZLD4.30 C0 or later version first before upgrading
to ZLD4.33.
Recommended upgrade to ZLD4.20 patch2 C0 or later version first before
upgrading to ZLD4.30.
Recommended upgrade to ZLD4.13 patch2 C0 or later version first before upgrade to
ZLD4.20.
to ZLD ZLD4.35.
Recommended upgrade to ZLD4.30 C0 or later version first before upgrading
to ZLD4.33.
Recommended upgrade to ZLD4.20 patch2 C0 or later version first before
upgrading to ZLD4.30.
Recommended upgrade to ZLD4.13 patch2 C0 or later version first before upgrade to
ZLD4.20.
Should I upgrade 5 times, 4.11 to 4.13, 4.13 to 4.20, 4.20 to 4.30, 4.30 to 4.33, 4.33 to 4.35 ?

Hi @SandB,
On our USG40, the firmware version on two firmware partition are 411AALA2C0.bin originally.
I load your configuration file to USG40 and upload 4.35 to the standby partition.
USG40 is successfully upgraded from 4.11 to 4.35 in our lab.
If you still have concerns about the firmware upgrading, remember to save the startup-config.conf of USG40 first and then upload firmware 4.35 to "standby" partition.
