Rolling back environments
After migrating to a WAS v8.0 environment, you can roll back to a v6.x or 7.x environment. This returns the configuration to the state that it was in before migration. After rolling back the environment, you can restart the migration process.
Supported configurations:
This topic is about configuration migration, such as migrating dmgrs and federated nodes in a network deployment environment. The Application Migration Toolkit for WAS provides support for migrating applications from previous versions of WAS to the latest product version. For information about migrating applications, read more about the Application Migration Toolkit. Generally, migration does not modify anything in the configuration of the prior release; however, there are cases where minimal changes are made that are reversible.
Procedure
- To roll back a v8.0 dmgr and its federated nodes to v6.x or 7.x, follow the instructions in Rolling back a WAS ND cell.
- To roll back a v8.0 federated node to v6.x or 7.x, follow the instructions in Rolling back a federated node.
- To roll back a v8.0 stand-alone application server to v6.x or 7.x, follow the instructions in Rolling back stand-alone application servers.
Results
The configuration should now be returned to the state that it was in before migration.
What to do next
We can now restart the migration process to do so.
