having an 4786 system in idle state (no connection, it's for testing the upgrade process before I start it on the productive system), I can't upgrade online to 5087:
- Under "System software update", I tried to upload the 5087 ISO. The GUI becomes gray and tells me something like "don't touch , wait for completion" . The next day, it*'s always gray, and no new version is uploaded.
- Under " Update downloader", I click CHECK. It runs, it tells that it's downloading and counts some MBs of download, and then, it's over and nothing has happened. BTW, something has happened: for each try, the "Available space " is reduced for some MB. Filled with download garbage, I guess.
Is this a known problem? I was in hope that update is possible instead of reinstallation and reconfiguration. But it seems not working (on a system without load!) Or do I something wrong?
