Prepare to Upgrade
NuoDB Upgrade Compatibility Requirements
A rolling upgrade to NuoDB 5.0 (or later) from a previous major release is supported from 4.2.5 (or later) or 4.3.1 (or later). For assistance with a rolling upgrade from any other previous major release versions to NuoDB 5.0 (or later), contact NuoDB Support.
|If upgrading with databases down, you may upgrade directly to NuoDB 5.0 (or later) from any version.|
NuoDB SQL Execution Engine Upgrade Consideration
If you are upgrading a production environment and your NuoDB database applications have not yet been tested or validated using the Vectorized Execution Engine (VEE), follow these steps.
Test and confirm that your applications work correctly on VEE in a test environment
Upgrade your production database to use VEE
Test and confirm that your production applications are running well on NuoDB 4.2 using VEE
Pre-Upgrade Best Practices
Before you upgrade to a newer NuoDB release, follow these best practices.
Stop a Storage Manager (SM) and run
nuoarchive checkon the archive of every storage group served by that SM. For more information, see NuoDB Archive - Checking.
Back up your databases. For more information, see Backing Up and Restoring Databases.
Determine whether you want to change any NuoDB configuration files to take advantage of New Features or Changes to features. Make the necessary updates to the configuration files on each upgraded host before you restart the Admin Process (AP) on that host. Installation of the new NuoDB release will not overwrite the existing configuration files
