Upgrading the MDEX Engine

To upgrade the MDEX Engine, you uninstall the existing version of the MDEX Engine and install the new version. Next, you provision the MDEX Engine using the mkmdex command.

To upgrade the MDEX Engine:

  1. Uninstall the previous version of the MDEX Engine, using instructions from the Latitude Installation Guide version 2.1.
  2. Install the MDEX Engine, using instructions from the Latitude Installation Guide version 2.2.x. If required, uninstall and install the Cluster Coordinator.
  3. Start and provision the MDEX Engine by running the dgraph and mkmdex commands. For information, see the Latitude Installation Guide version 2.2.x.

After you are finished, you should have an MDEX Engine running with an empty MDEX Engine index.

Proceed to upgrading the Latitude Data Integrator (LDI) Designer.
