After you have prepared your cells for migration and ensured
that you have met all prerequisites, migrate the deployment manager.
Before you begin
To Migrate WebSphere® Extended
Deployment Compute Grid Version 6.1.1 or above to
Version 8.5, you must have WebSphere Extended Deployment
Compute Grid Fixpack 3 and cumulative interim fix PM39203 installed.
Migration from any version of the Feature Pack for Modern Batch 1.0.0.x
is supported.
About this task
You must migrate the deployment manager first. To migrate
the deployment manager, perform the following steps:
Procedure
- Backup your modern batch configuration on the deployment
manager node. Use the provided migrateWCGConfigTo85.py
script to export the configuration data. After the migration is completed,
you will use this script again to restore your configuration, which
automatically makes all necessary changes to convert between releases. Change directories to your cell’s deployment manager configuration
file-system, and execute:
./bin/wsadmin.sh -lang jython -f migrateWCGConfigTo85.py \
--backup [-configBackupDir /path/to/backup/location]
- Install WebSphere Application Server Version 8.5.
- Migrate your old deployment manager to WebSphere Application
Server Version 8.5. You
can use the migration tools to migrate your old deployment manager
to Version 8.5.
- Use the --wasmigrate option of the migration script. For example:
Perform --wasmigrate on your migrated Dmgr (from
its WAS_HOME/bin dir)
wsadmin.sh -conntype NONE -lang jython -f .migrateConfigTo85.py --wasmigrate -oldWASHome
<oldWASHome> -newWASHome <newWASHome> -cellName <cell> -nameOfProfile <profile>
-configBackupDir <PathToBackupLocation> -level <level>
- Ensure the previous version Compute Grid or Feature Pack
nodes are stopped.
- Start the new deployment manager.
- Restore your saved configurations on the deployment manager. To restore a configuration, run the following script:
./bin/wsadmin.sh -lang jython -f migrateWCGConfigTo85.py \
--restore [-configBackupDir /path/to/backup/location]
Avoid trouble: The configuration now stored in your deployment
manager is incompatible with your non-migrated nodes at this time.
Do not synchronize your nodes until after you have finished migrating
them. Do not restart any non-migrated servers and node agents after
this point.
