I have a GSM7312 running a very old software version - 3.0.3.2. Latest available version is 6.2.0.14. In the release notes there isn't a word about proper upgrade paths. So questions:
1) Is it safe to go from version 3 to version 6?
2) Do I need to do a factory reset or something after the upgrade? I know a lot of devices change config formats and mess up their configs if not resetted.
3) Is there any official support channel for business devices besides this community btw?
Just to verify. Is your switch model really a GSM7312? It is because there is no firmware v3.0.3.2 for the GSM7312. As reference, kindly check the GSM7312 Firmware and Software Downloads page here.
The firmware v3.0.3.2 is for the GS108Tv1 (v = version). As reference, kindly check the GS108Tv1 Firmware and Software Downloads page here.
Support team tells me "we can't provide you 5.x, go for the lowest 6.x and upgrade sequentially to the latest version". I don't think I'll play this game of poker 🙂
The link to the old firmware versions for the GSM7312 were removed. However, I found the link to the GSM7312 firmware v5.1.1.3. Kindly download it here and upgrade the switch firmware. Afterwards, do a ladderized upgrade to firmware v6.0.0.15 up to the latest firmware which is v6.2.0.14.
Note: Please read the instructions and release notes on the zip file.
Yep, support team found it as well 🙂 The thing is that in 6.2.x release notes there is nothing about upgrade paths, etc. so I was worried for a reason. We'll buy a backup switch before we attempt any upgrades, that is for sure.
