We need to change default location of storage for nexus, kindly help us with standard process to get it done.
CA Release Automation 5.x - 6.x
CA Release Automation includes a Nexus Sonatype repository so to store artifacts that are critical to the availability and features of CA Release Automation. Examples of this are action pack files and many other jar files needed by the management server, execution server and agent machines.
When the Sonatype Nexus repository used by the CA Release Automation server runs out of disk space it is often related to storing deployment artifacts in this repository. What is meant by deployment artifacts are the artifacts that are built via integrations (like TFS, TeamCity, etc...) and then deployed by CA Release Automation. It is not recommended to store your deployment artifacts in the Sonatype Nexus repository used by CA Release Automation - especially for environments with many new artifacts and deployments. It is recommended to store your deployment artifacts in an official supported artifact repository tool like Sonatype Nexus Professional or Artifactory. Some of those integration build tools (like TFS and TeamCity) have artifact repositories that can be used too. They might have their own recommendations on usage so it is recommended to check with them to see if there are any limitations or best practices.
