When running LiveCycle Configuration Manager to configure and deploy LiveCycle ES2, make sure that you skip the Form Template Import step. Having completed your upgrade process, ECM Connector services could be in a stopped state because of a mismatch between ECM connectors' client and server versions.

LiveCycle ES2 supports your LiveCycle ES 8.x ECM Connector server version and the machine stays unchanged
Configure your application server per your upgrade type (in-place or out-of-place) with respect to the client version already installed. See Preparing to Upgrade to LiveCycle ES2 from 8.x for more information.
