Upgrading between major versions

There are a few extra steps to take beyond those outlined in Upgrading an existing installation when upgrading to a new major version line.

Configuration updates required when upgrading to CLC Genomics Server 22.0 or higher

If you have configured custom listening port or SSL settings, these need to be reconfigured after upgrading to CLC Server 22.0 and above from older release lines (21.x and earlier), due to an update to Tomcat.

When upgrading, a backup of your previous configuration will have been saved to conf/server.xml.backup, under the installation area. This file can be referred to for information relevant for configuring the new conf/server.xml file.
