During the upgrade process, the upgrade program does the following:
Note
V2110 (MS Hyper-V platform) does not support flash functionality.Note
When you upgrade the Wireless Controller Software, the previous SSL Configuration file is replaced by a new one. Consequently, the manual edits that were made in the previous SSL Configuration file are lost. If you have done manual edits to the SSL configuration file to install certificates for Captive Portal on the virtual interfaces, it is suggested to use EWC Captive Portal Certificate Configuration instead.If you are running a software version earlier than V9.01, you must first upgrade to V9 before upgrading to V10.
Use the following matrix to determine the upgrade path to required version V9 that is appropriate for your wireless controller and the software running on it.
