Upgrading Alfresco general procedure

This section describes the procedure for upgrading from a previous version of Alfresco. The process involves a new installation of the Alfresco binaries and configuration, and an in-place upgrade of a copy of the repository.

In-place upgrade of the Alfresco binaries and configuration is not recommended. This is because if anything goes wrong during the upgrade process, you can use your previous Alfresco installation.
These steps assume that you have an existing Alfresco installation (alfresco-v.1) with the following settings:
File Name Properties dir.root=/alfresco-v.1/alf_data db.url=url<v.1> data.dir.root=/alfresco-v.1/solr/myindexes
  1. Install the new version of Alfresco.
    1. Shut down your existing Alfresco instance.
    2. Back up your existing Alfresco repository (alfresco-v.1) and the database. See Backing up the Alfresco repository.

      Note: Back up any configuration overrides from the <extension> directory.
    3. Use the setup wizard/installer to install the new version (alfresco-v.2) of Alfresco into a different directory from the existing installation. See Installing Alfresco using setup wizard.

      For example, the new Alfresco installation will have the following settings:

  2. Validate the new Alfresco One 4.2 installation to check that it is working correctly.
    1. Configure the new installation with a new repository and database (not the existing one).
    2. Start Alfresco and validate that the system works correctly.

    For more information, see Validating the upgrade.

  3. Apply all customizations to the new Alfresco One 4.2 installation.
    1. Stop the Alfresco server.
    2. Remove any unwanted applications.
    3. Modify Alfresco applications.
    4. Install the required AMP files. See installing an Alfresco Module Package.
    5. Do not copy the files. Copy only the override settings so that you will not overwrite the new extension files in the upgraded version.
    6. Start the Alfresco server.

      Monitor the startup log messages for information on the status of the upgrade. If any issue(s) occur in the logs during startup, you need to rollback the whole repository to fix the issue(s) and then try again.

    7. Fully test the working and configuration of your customizations.
    8. Stop the Alfresco server.
  4. Restore production data.
    1. Remove all the files and directories under the contentstore directory of the new installation. Also, delete the database.
    2. Delete the files in the two Solr alfrescoModels directories, and the indexes in the two directories (solr/workspace/ and solr/archive/) of the new installation.
    3. Restore the backup of the indexes, contentstore directory, files, and database from your previous Alfresco installation into the new installation. See restoring production data.
    4. Start the Alfresco server.

      If any issue(s) occur in the logs during startup, you need to rollback the whole repository to fix the issue(s) and then try again.

  5. Once you are happy with the upgraded system, remove the old Alfresco installation and repository.
