Recently performed an upgrade recently from Project Server 2007 to 2010.  All preupgrade checks were clean and the upgrade completed with no errors at all.  What we did notice, however, if you drilled into a project from Project Center, the entire left hand Action Pane would completely disappear.  No links to Resource Center, Business Intelligence Center, or anything else was visible.  COMPLETELY BLANK.  We ended up opening a ticket with Microsoft.  The technician and I ran the PowerShell commands below individually.  Once finished the Action Pane disappearing act was no more!


Run each command individually:

$Web = get-SPWeb http://<serverName>/<instanceName>

$Web.AllProperties | Format-Table
