Hi.
We have SG300-10MP switches running 1.1.2.0 and 1.3.0.62. I want to upgrade to latest version 1.4.9.4. In release notes for version 1.4.9.4, it is written that switch first must be upgraded to version 1.3.5.x, but this version is not available for download. Only 1.1.x.x and 1.4.x.x versions are available for download.
It is also written in release notes that boot software has to be upgraded to 1.3.5.06, but this boot software version is also no available...

From release notes;
Upgrading from Versions Earlier than 1.3.5 When upgrading the device from version prior to 1.3.5: • For Sx200/Sx300 models, first upgrade the device image to image version 1.3.5.x and upgrade the boot file to 1.3.5.06
