There are two ways to upgrade your NuoDB database:
Caution: After upgrading from 2.6 to 3.0, you will need to clear your browser cache to view the new icons.
Shown here is a quick reference upgrade table to help you:
|Rolling to this Version|
|Upgrading Version from/to||2.1.x||2.2.x||2.3.x||2.4.x||2.5.x||2.6.x||3.0.x|
In a domain with one broker, choose Upgrading With Databases Down.
If your domain has at least two brokers and each database is served by at least two transaction engines and two storage managers, then you can choose whether or not to shut down databases during the upgrade:
Caution: Once the database version has been upgraded, NuoDB does not generally support downgrading to a previous release.
Note: For information on Downgrading, see Downgrading to a Previous Release.
