We plan to upgrade our servers to HSphere 3.4 starting Saturday, November 27, 2010 at 11:30 PM EST.
Control panel will be stopped for 4 hours for the upgrade to complete, and individual services may not be available intermittently during this time. Servers may be out of communication with the control panel for a longer period of time, which only means there may be a delay in using control panel.
This is primarily be a bug-fix update. There are certain new features that this upgrade allows to make available. However, their final availability will be announced separately.
Well on the windows side, the servers are up, which is the good news, but it is going to be a bit before connected to CP fully, while it upgraded the core it is failing on upgrades of feature packages and I am doing them manually.
SD servers worked well, shared seem to have more in features in use that are locking files from upgrading.
