I read somewhere
"When you want to upgrade Teamsite from 6.7.2 to 7.2.1 you must run the installer twice. The first time, all components except for the Administration UI are installed;the second time, the Administration UI is installed".
Do I need to follow the instruction on the screen (upgrade teamsite, restart server and stuff), or do I need to stop the installer at some point and restart the installer?
Because i have already done the upgrade now, and nothing works
