Firmware Upgrade Path

#1

UCM6104 current FW 1.0.6.10. I need outbound route time restrictions so I am forced to update. Question is whether I can jump directly to 1.0.9.97 (the oldest version posted on the GS fw website) or to a later version (i.e. 1.0.14.24).

I know I’ll have to hop version-by-version between 1.0.15.16 and 1.0.18.13, but there are no release note for fw before 1.0.15.16.

it is always recommended to do all the intermediate steps

I believe you can upgrade to 1.0.9.26 without issue. I have attached a link to some release notes as 1.0.9.97 was a transition firmware to update Asterisk to a later version.
