For a single CLC Server, the steps we recommend when upgrading to a new version are:
Upgrading an existing installation
- Stop the CLC Server service after making sure that nobody is using the server. Mechanisms to help with this, including sending a message to users logged into the CLC Server, can be found in Server maintenance. Getting information about who is logged in is described in User statistics.
- Install the CLC Server software in the same directory the existing version was installed in. All settings will be maintained, for example, the locations data are stored, Import/Export directories, BLAST database locations, Users and Groups, and External Application settings.
If you have a job node setup, you will also need to upgrade the CLC Server software on each job node. Upgrading the software itself on each node is all you need to do. Configurations for job nodes, as well as new or updated plugins, are pushed to them by the master node.
When upgrading between major versions, the extra steps described in Upgrading between major versions must also be taken. Major version lines are denoted by the first number in the version. For example, upgrading from software with version 21.0 to version 22.0 involves an upgrade to a new major version line.
