Upgrade Notes

For all upgrades

  • Always make sure the database has been properly shut down and the transaction log (virtuoso.trx) is empty before performing any update/upgrade. This is easily done by launching Virtuoso with the extra command-line argument, “+checkpoint-only”. Virtuoso will launch, replay the transaction log, run a checkpoint (which zeroes the transaction log), and exit cleanly.

  • Before upgrading any database, it is always a wise precaution to make a proper backup.

Upgrading an existing Cloud Instance Virtual Machine

Execute the relevant command for your operating system distribution:

  • Ubuntu and related — apt update && apt upgrade
  • RedHat and related — yum update

Manually overwriting an older binary with the latest edition

Start with the documentation of manual upgrades.

If you choose to manually replace the Virtuoso server binary (virtuoso-iodbc-t) in-situ, you MUST also update the libraries in the Virtuoso hosting/ subdirectory due to incompatibilities between the latest binary and previous plugin versions. We also strongly RECOMMEND that you update the VAD packages in the vad/ subdirectory.

Upgrading from any previous version to the latest version

For best results with existing installations, we recommend following our simple step-by-step guide to upgrade from any previous version of Virtuoso to the latest version.
