I was able to upgrade and publish the topology from a non-lync machine as suggested. now on one of my lync FE servers when I try to do the upgrade it gets to the step "Uninstalling roles" and it failes. the error at the bottom says "Error encountered: Error returned while installing Server.msi(RegistrarStoreUpdate, Feature_Server, Feature_Server_Update), code 1638
please help. I no longer have IM in my company now
