Common Operations › Migrating Applications Between Grids

Migrating Applications Between Grids

You may want to migrate an application instance from one grid to another. For example, an application may need to be migrated because:

• It needs more resources and the grid on which it resides doesn't have more.
• Other applications need more resources and you want to free us some.
• The grid where the application resides is being decommissioned or prepared for maintenance.

Be aware of the following:

• In the first two cases, you can also add more servers to the grid, up to the maximum supported number of servers (32 in version 1.2.3).
• You must stop the application during the migration process.

You can migrate an application using the Application Migration Wizard or the application migrate shell command.

Important: Before an application can be migrated, trust must be set up between the two grids. For more information, see Setting up Trust Between Two Grids.

For procedures that describe how to migrate applications between grids, see the following:
