Migrating
Successful migration requires significant planning and preparation, understanding the tools that are involved, and careful execution of the appropriate steps in the order provided.
Setting up the target environment
The migration requires you to install the required Portal and WebSphere® binary installations. To prepare your target environment, ensure that you have applied the latest cumulative fix and the most recent fix pack before you start migration. In addition, create new copies of the source databases for the target environment to use, and prepare the target environment for any custom applications that have dependencies or any other tasks that need to be performed for remote or cluster migrations.
Database considerations
Depending on the type of database that you use, there might be extra considerations or tasks to complete before and after you migrate your data. Review the information that is tailored for your database type to ensure the migration process completes successfully.
DB2 database migration considerations
Database migration is one of the most time consuming portions of the migration process. If you are migrating from DB2®, review the following topics to improve the speed of the database migration process.

- Backup and restore
  Backup and recovery of data files and databases is an essential operation for any business system, particularly for data and applications that run in production environments. Create and follow a plan for backing up and recovering data on all tiers of your HCL Digital Experience deployment. IBM Installation Manager must also be included in backup and recovery planning. If you back up the HCL Portal file structure and then install a fix pack, your HCL Digital Experience and IBM Installation Manager become out of sync after you restore the HCL Portal file system. This condition is not recoverable.
- Migrating
  Successful migration requires significant planning and preparation, understanding the tools that are involved, and careful execution of the appropriate steps in the order provided.
  - Overview
    Migration is the process of collecting configuration data and applications from an earlier installed version of HCL Digital Experience and merging them into a newer installed version. So that the new environment is identical to the earlier environment. For the z/OS® platform, the new version must be on the same server as the earlier version. Migration to a different (remote) server is not supported.
  - Planning for migration
    Completing a thorough plan before migrating to the latest version of HCL Digital Experience has a direct impact in the effort invested during the actual migration. Become familiar with the environment you are migrating to (target environment). Also, make sure that the environment you are migrating from (source environment) is up to date with fixes and meets the requirements for migration.
  - Preparing your source environment
    Before you begin the steps for migration, you must perform some critical tasks on your source environment, such as creating back ups, installing the latest cumulative fix and one of the two most recent fix packs, and disabling automatic synchronization if you are migrating a cluster. Review the topics in this section, and perform the required tasks to ensure that your source environment remains functional and the migration completes successfully.
  - Setting up the target environment
    The migration requires you to install the required Portal and WebSphere® binary installations. To prepare your target environment, ensure that you have applied the latest cumulative fix and the most recent fix pack before you start migration. In addition, create new copies of the source databases for the target environment to use, and prepare the target environment for any custom applications that have dependencies or any other tasks that need to be performed for remote or cluster migrations.
    - Target environment considerations
      Installation planning of the target environment must be part of your overall migration planning. There are some considerations to keep in mind when you install HCL Portal and you plan to do a migration from your existing installation.
    - Installing Portal and WebSphere binary files
      On your target system, you must install the portal and WebSphere® binary files.
    - Installing fix packs on the target environment
      Periodically, fix packs are released to integrate product code fixes. Between fix pack releases, there are interim fixes to ensure product reliability and stability. You must apply the latest available fix pack and cumulative fix to the target environment. The Recommended fixes link provides links to fix pack and interim fix downloads. There is also information about what is recommended and what is required.
    - Copying portal binary files to the deployment manager
      Complete this task if the deployment manager is not sharing application binary files with a Portal install.
    - Copying files for third party and custom applications
      The Portal migration attempts to install custom applications in the target environment, but it does not automatically copy the files required for those applications. If the files are not copied over, it is possible that the applications will fail to install or not work properly.
    - Maximum open file descriptors for Unix-based platforms
      For Unix-based platforms, the default open file descriptor must be set to 200000 to allow the Configuration Wizard commands to run properly during migration.
    - Copying files for third party and custom applications
      To keep the earlier portal environment in production and reduce the amount of downtime during migration copy the earlier portal server JCR and Release domains. Connect to the domain copies and then update the new portal server with the domain copies. The process of connecting to the domain copies must be done after you upgrade the ConfigEngine tool but before you upgrade the Portal profile.
    - Database considerations
      Depending on the type of database that you use, there might be extra considerations or tasks to complete before and after you migrate your data. Review the information that is tailored for your database type to ensure the migration process completes successfully.
      - Configuring transaction logging space
        When you migrate from earlier versions of Portal, certain portions of the actual database migration use database transactions that can contain large volumes of data change. In order for the database to accommodate these transaction changes, the amount of space available to the database transaction logs might need to be increased.
      - Oracle: Disabling the auto space advisor background task
        To prevent deadlocks during migration, you must complete a task to disable the Oracle background task called "Auto Space Advisor" before your run the upgrade-profile task during migration using the Configuration Wizard. After you complete migration, you can enable "Auto Space Advisor" as a post-migration task.
      - DB2 database migration considerations
        Database migration is one of the most time consuming portions of the migration process. If you are migrating from DB2®, review the following topics to improve the speed of the database migration process.
        Update database statistics
        Statistics are information that is collected about the contents of the database tables and indexes. They are used by the cost-based optimizer in the database to influence the approach (query plan) that is used to run SQL queries. By collecting updated or new statistics, you provide the database optimizer the most up-to-date information about the tables and indexes. Therefore, the query execution plans are generated as efficiently as possible.
        Preparing DB2 for large data sets migration
        If you use DB2® and have a large amount of content in the JCR repository (for example, Web Content Manager data), prepare the DB2 for migration. You must update several settings that are related to performance.
  - Migrate data using the configuration wizard
    For Version 8.5, data, applications, databases, property files, security settings, and configuration are migrated using the Configuration Wizard. Use the roadmaps for cluster and stand-alone environments to guide you through the process.
  - Next steps
    To complete migration, you must first perform several post-migration steps that depend on how Portal is being used. After completing the post-migration steps, review the Enabling new functionality section to take advantage of the new tools available in HCL Digital Experience 8.5. Enabling new functionality should not be started until all post-migration steps have been completed.
- Integrating
  Integrate HCL Digital Experience with software such as HCL Sametime to enable your users to collaborate more easily. You can also use the unified task list portlet to integrate HCL with your backend business process software, such as IBM Process Server.
- Administering
  Use the administration tools that are provided with the HCL Digital Experience to do various day-to-day administration tasks.
- Securing
  Security tasks include setting up property extension databases and custom user repositories, configuring and activating SSL, and configuring authentication. In addition, tasks such as activating Federal Information Processing Standards (FIPS) and NIST SP800-131a security modules and configuring external security managers such as Security Access Manager might be required to secure your portal environment.
- Monitoring
  HCL Portal includes tools and features to help you monitor the portal site.
- Setting up a website
  Setting up a website includes, creating pages, adding navigation, setting up search, and adding content to the site. Themes are used to customize the portal's look-and-feel. Out-of-the-box templates and the site wizard can help you set up your portal site faster. You can add wikis and blogs to your site and let users tag and rate content on your site.
- Staging to production
  During portal solution development, the solution is initially developed, tested, and refined on one server or a limited number of servers. The solution is deployed later on live systems, referred to as the production environment. The process of moving the solution from the development environment to the production environment is called staging.
