With the release of Nexus Repository 3.1, the repository manager consists of a new default file structure simplifying the work needed to upgrade or manually backup components and configurations.
Keeping the default location of the data directory outside of the installation directory will prevent two common errors:
- Unpacking new installations directly on top of existing installations.
- Accidentally deleting or damaging work directories when attempting to move them out of old installations.
To see which files you need to overwrite during an upgrade from 3.0.2 to 3.1.0 review these special instructions.
Here’s a reference comparing the configuration files in 3.0 versus 3.1.
