Installing a fresh code base will also allow you to evaluate your local modifications and configuration changes as you migrate to 5.0. These old files will still be detected by RT in some cases and will cause issues. We moved some things to new locations and old files are not removed as part of the upgrade process. We recommend this approach because of the large number of changes to the code base for this major release. Then import your existing database and run the database upgrade steps using make upgrade-database. Instead, do a fresh install into /opt/rt5 (or your custom location) for the code portion of the upgrade. Upgrading to RT 5 over an existing RT 4 installation (/opt/rt4) is not recommended and will almost certainly cause issues. Alternatively, you could import a backup of your database as rt5 to conform to the new default, although this isn't required. If you are upgrading, you will likely want to specify that your database is still named rt4 or even rt3. RT now defaults to a database name of rt5 and an installation root of /opt/rt5. See devel/docs/UPGRADING-5.0 for internals changes relevant to extension writers, including deprecated code. Read this section carefully before you upgrade and look for changes to features you currently use. The following lists some of the notable changes, especially those that might require you to change a configuration option or other setting due to a change in RT. This package is distributed under the MIT license.The 5.0 release is a major upgrade and as such there are more changes than in a minor bugfix release (e.g., 4.4.0 to 4.4.1) and some of these changes are backward-incompatible.
