Preparing to Upgrade
Before you upgrade to a newer NuoDB release, best practices include the following steps:
- Stop an SM and run

nuoarchive check on the archive of every storage group served by that SM.
- If there are no errors, you may upgrade your database using either the upgrade with databases down method or the rolling upgrade method. For an overview of the upgrade methods available, see Upgrading to a New Release.
- Back up your databases. For general information on backing up NuoDB databases, see Backing Up and Restoring Databases.
