In order to migrate WCS data to Cisco PI 2.1, the first step is to upgrade WCS from old version to version 7.0.230 or higher.
I followed instruction here http://www.cisco.com/c/en/us/td/docs/wireless/wcs/7-0/configuration/guid... . After selecting 'Upgrade' option from InstallAnywhere window, the process started to install, but later it was hung at 'Preparing Data for Migration' step. After a long time, the process stopped and the InstallAnywhere window closed by itself.
Is there anyone has the same problem?
