WebSphere Application Server -Migration & Upgrade - L2 & L3

Explore remote migration from 8.5 to 9.0 on different hosts and the create remote migration jar method, including its pros, cons, and when to use.

Plan pre-migration checks, back up your WebSphere environment, confirm OS and Java compatibility, schedule downtime, and execute in-place upgrade to 9 with post-upgrade validation and rollback readiness.

Master side-by-side migration in WebSphere by performing local backups at multiple levels—profile backups, full app server backups with tar or zip, and optional Veeam—enabling safe migration and rollback.

Execute a side-by-side migration from was 8.5 to 9, including backups and pre-upgrade checks. Use the free upgrade path for licensed installations and optimize file handles to 10,000.

Migrate a WebSphere profile from 8.5 to 9.0 using the post upgrade tool, applying backup configurations and validating migrated units, deployment, and port numbers 9060 and 9080.

Plan and execute a side-by-side migration for the dmgr and federated nodes from 8.5 to 9.0, validate migrated profiles, implement backups, document JVM changes, and prepare rollback steps.

Perform the pre-upgrade steps for WebSphere migration, verify backups, stop services, and save migration backups to DMG profiles for DMGR and managed node.

Perform post-upgrade validation of the deployment manager and managed node by federating the migrated profile, validating cell and node names, syncing nodes, and confirming application operation.

Demonstrate in-place migration from WebSphere 8.5 to 9 using the IBM Installation Manager GUI, including profile creation and backups.

Create dmgr and app server profiles on a target host. Align cell and node names, enable admin security, and verify 9060 and 9043 ports as part of migration preparation.

Perform a pre-upgrade migration backup for WebSphere App Server on the source host, backing up profiles BMR 85 and app SV 85, then copy backups to the target server.

Back up the current application server and migrate WebSphere from 8.5 to 9 on the target host. Verify the migrated DMGR profile and node agent, and validate application deployment.

Generate a migration jar for WebSphere App Server 8.5 to 9.x with the script, then transfer the jar to the source server via scp or winscp per the info center.

Execute the pre-upgrade for IBM WebSphere App Server 85 by extracting the migration jar on source, backing up the profile, creating a new profile, and running the upgrade command.

Execute the post-upgrade workflow for a migration backup on target and test the configuration. Deploy the updated app server, monitor logs, and confirm access through the new profile.

Apply a fix pack to the WebSphere Application Server using the initial command and a jar from repository, stop services, and install in silent mode, upgrading from 8.5.4.2 to 8.5.5.0.

Install IBM WebSphere in silent mode using the installation manager to record a response file, specify repositories and installation location, apply fix packs, and verify success via the post log.

Learn to manage IBM SDKs with the managesdk command, list and enable SDKs, set per-server or per-profile defaults, and switch SDK versions across apps using the admin console.

Discover alternate migration methods for WebSphere administration, from fresh install with manual configuration to blue-green and hybrid migrations, including VM snapshots or cloning, selective export/import, and deployment automation.
