Caveats

Upgrading to 9.1.0 from any previous version
  • The default Alpaca store location has been moved from /tmp/alpacastore to /var/alpaca/store. If your Alpaca installation includes a configuration for alpaca.file-store.location, this new default will not overwrite that. This change will only affect users who did not specify an Alpaca store location and are using the default. For those who used the default directory, you will need to manually move the contents of /tmp/alpacastore to /var/alpaca/store.
  • The following configurations have been removed: alpaca.file-store.cleanup-interval and alpaca.task.retention-period-days. They have been replaced with alpaca.file-store.temp-file-retention-period-days, alpaca.file-store.task-file-retention-period-months and alpaca.file-store.report-file-retention-period-months.
Upgrading to 9.0.0 from any previous version.
  • RabbitMQ is a required part of the Alpaca system for version 9.0.0 and following. Please follow the installation guide to complete the RabbitMQ installation.
  • There is additional configuration required for connection to Eureka, RabbitMQ, and the optional Amazon S3 bucket support. Please follow the configuration guide and update the /etc/alpaca/server/config/application-prod.yml file accordingly.
  • Note that upgrading to Alpaca 9.0.0 will remove any Recurring (scheduled) Tasks that are configured.
  • Please note that in the application-https.yml that the ECDHE_RSA_WITH_AES_256_CBC_SHA384 cipher has been renamed TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384. This means that if the https configuration is moved from the Server to the Gatway that the cipher needs to be renamed.
  • Note that if using a Highly Available Clustering setup (HA), the SSL configuration has been moved from the Alpaca Server configuration to the Alpaca Gateway configuration.
Upgrading to 8.1.0 from any previous version.
  • In 8.1.0 the configuration that was previously uc-one is now cisco-soft-client. Property files that contain the old uc-one tag will need to be updated.
Upgrading from 7.2.X or earlier to 8.0.0 or higher

  • If running Alpaca 7.2.0 or earlier, an incremental upgrade to Alpaca 7.2.1 is required before upgrading to 8.0.0 or higher. After the update to 7.2.1, shut off Alpaca, and then upgrade to Java11 before upgrading to Alpaca 8.0.0 or higher.

  • If using an existing /plugins directory for Alpaca. This directory will need to be backed up manually and the plugins re-added to the Alpaca plugins directory.

Upgrading from 7.0.4 or earlier to 7.1.0 or higher
  • Back up all configuration files in /opt/alpaca/config/.
  • After upgrade, configuration files will be located in /etc/alpaca/<ALPACA_PACKAGE>/config/.
    • The backed up configurations files will need to be copied here.
  • After upgrade, log files will be located in /var/log/alpaca/.
