This procedure assumes that Communications Server 1.5 is installed in source-install-dir. The default domain, domain1 is running. Deployed applications, clusters, and node agents are also running. The following procedure enables you to upgrade the configuration of the default domain.
Install Communications Server 2.0 in target-install-dir. This installation should have the same profile has the Communications Server 1.5 installation in source-install-dir.
Navigate to the config directory of the Communications Server 2.0 installation.
cd target-install-dir/config
Open the asenv.conf file. Point the AS_ACC_CONFIG and AS_DEF_DOMAINS_PATH variables to corresponding Communications Server 1.5 locations as follows:
AS_ACC_CONFIG=source-install-dir/domains/domain1/config/sun-acc.xml
AS_DEF_DOMAINS_PATH=source-install-dir/domains
Stop the Communications Server 1.5 node agents and domain.
Start the Communications Server 2.0 domain.
The command to start the default domain is as follows:
cd target-install-dir/bin
target-install-dir/bin>asadmin start-domain domain1
Start the Communications Server 1.5 node agent from the Communications Server 2.0 installation.
target-install-dir/bin>asadmin start-node-agent -syncinstances=true --agentdir source-install-dir/nodeagents/ node-agent-name
Repeat this step for all node agents on the domain.
Launch the deployed applications.
There is no need to stop and restart the clusters, instances, and databases.
