The java version required by the new version of Squore may be different from the one you were using in your previous installation. On Windows, an installer screen will prompt you for the path to the new Java installation to use after upgrading. On Linux, you can use the -J option to specify the new path to Java in your upgrade command line.

Before upgrading from a pre-16.0 version, ensure that you have as much free space on your disk as the size of your current database, as reported on Administration > Projects.

Folders inside the installation directory are deleted during an upgrade, including the default tmp, data, cluster and backup folders. Before you attempt to upgrade Squore, run a full backup of your data (and move it outside <SQUORE_HOME>) using the provided backup scripts described in the section called “Backing-Up the Squore Data”

On Linux, if you used the -x and/or -s parameters in your initial installation or if you manually edited the value of PostgreSQL's shared_buffer or java Xmx parameters after installing, you must pass -x and/or -s on the command line for the upgrade as well, as they are not read from the previous installation. For more details on install options, refer to install(1).

The file postgresql.conf in your database cluster is patched during the upgrade process. If you have modified it manually, create a backup copy before upgrading and verify that the migrated file still contains your modifications.

If you are a local PostgreSQL cluster as your database, ensure that the server and the database are shut down before continuing. In all other scenarios (an Oracle database or a remote PostgreSQL cluster not managed by Squore) ensure that Squore Server is stopped and that the database is accessible and accepting connections.

No progress information is displayed on screen during the database upgrade phase, which may take a while to complete.
