MarkLogic 12 supports upgrades from MarkLogic 10.
During the upgrade, the Security database, the Schemas database, and the configuration files are automatically upgraded. The Security database is upgraded with the latest execute privileges, and the Schemas database is upgraded with the latest version of the Schemas used by MarkLogic Server. The upgrade occurs as part of the installation procedure.
Databases that contain your own content are also upgraded. Once you upgrade, you can no longer use that database with previous versions of MarkLogic Server.
Note:
- We strongly recommend performing a backup of your databases before upgrading.
- We also recommend that you first upgrade to the latest maintenance release of the major version of MarkLogic Server that you are running before upgrading.
For the upgrade procedure, see Upgrading from Previous Releases. For details about known incompatibilities, see What's New in MarkLogic 12.
