Migration tasks
Task Description Status Install WAS v8 on test system Build a complete WAS ND cell configuration and verify that it works correctly before you attempt to migrate an existing cell or node. This process ensures that the system has all of the necessary prerequisites and supports the new level of WAS.
Install WAS v8 on remainder of new dmgr and node systems
Save and sync any unsaved changes in the WAS v6/v7 dmgr
Pending Update existing systems to latest fix level
Pending backupConfig on v6.1 systems Run for dmgr and each federated node Pending On v8.0 dmgr, node agent, and appservers, set profile owner Set ownership of the profile directories to be the same as the user under which WAS is to be run. Run before starting servers. Pending Start the WAS v8.0 dmgr
Pending Migrate stand-alone application servers TBD Pending Migrate dmgrs TBD Pending Migrate federated nodes TBD Pending Troubleshoot
Pending Rollback and restore If it fails, rollback environment, run a restoreConfig, and then rerun the migration process Pending Migrate web server configurations
Pending Verify LTPA security settings are set appropriately.
Pending Upgrade ITCAM and reconfigure on migrated nodes
