Upgrade a Grid to a Different Major or Patch-Incompatible Release

Generally, all patch set (and patch) releases of the same major release of TimesTen are patch compatible. For exceptions or upgrades to a different major release, you need to migrate the data from your current databases to databases in a different grid, one based on the target upgrade release.

To upgrade a grid to a release that is patch incompatible with your current release, perform these tasks:

1. Install the TimesTen distribution of the target release, as shown in Installing TimesTen Scaleout.
2. Using your new TimesTen installation, set up a new grid and databases to import the data of your current databases, as shown in Setting Up a Grid and Creating a Database.

   Note:

   The new grid does not need to match the topology (K-safety value and number of replica sets) of your current grid.

3. Export the data from your current databases and import it into the databases of your new grid, as shown in Exporting and Importing a Database.
4. Optional: Destroy your previous grid, as shown in Destroying a Grid.
