Hello,you can find and download the software for your Aruba switches from the Aruba Support Portal (ASP).Here is a link for the 3810M's available versions:
https://asp.arubanetworks.com/downloads;search=3810M;sort=VERSION_DESC;fileTypes=SOFTWARE;products=Aruba%20Switches;fileContents=SoftwareOnce you have downloaded the software the easiest way to do the upgrade is via the Web GUI. You can upload the software to the device and reboot the switch at a later time not to disrupt the network users. (until this reboot the switch will be still using the old version) The whole downtime will be just the time necessary for the switch to reboot.If you have disabled the Web GUI for security requirements or other reasons you can do the update via CLI using TFTP, the USB port or XMODEM.
The procedure via CLI is described here:https://techhub.hpe.com/eginfolib/networking/docs/switches/WB/15-18/5998-8162_wb_2920_mcg/content/ch09s03.htmlTo update a stack the procedure is the same, you connect to the commander and proceed like it's a standalone device. The other members will get their software from the commander. HTH,
Is the software version KB.16.11.0004 the recommended and stable one by Aruba? if Yes, can I just upgrade the current firmware (16.05 & 16.04) of 3810M & 2930M directly to 16.11.0004?Same with Aruba 2530M , current firmware 16.10.0002, can I upgrade it directly to 16.11.0004?Do you know any reference of the upgrade path please ?Thanks
