Considerations for migrating to a different operating system or from 32-bit to 64-bit
To migrate to a computer with a different operating system, or to migrate from a 32-bit computer to a 64-bit computer, you must perform more migration steps.
To migrate to a computer with a different operating system, you must install IBM Business Automation Workflow V19.0.0.3 on a third computer with the same operating system as the migration source computer (for example, Windows if you are migrating from Windows to Linux). Then, run the BPMCreateRemoteMigrationUtilities command to create a compressed file that you can use on the migration source computer. Copy the file to the source computer.
- You must install IBM Business Automation Workflow on an operating system version that V19.0.0.3 supports. If your source system is on an operating system version that is not supported, use a supported newer version of that operating system for the third computer mentioned in the preceding paragraph.
- If V19.0.0.3 does not support your source operating system type, you cannot use the business data migration method. However, you can still do artifact migration. For more details, see Migrating artifacts to IBM Business Automation Workflow.
To migrate from a 32-bit system, run the BPMCreateRemoteMigrationUtilities command on your 64-bit IBM Business Automation Workflow V19.0.0.3 system, but use the command with the 32bit parameter when you are creating the files for the source system. V19.0.0.3 supports 64-bit platforms only.
Business Automation Workflow V19.0.0.3 or later requires Java Runtime Environment (JRE) 8. If your 32-bit system does not support Java 8, you must either upgrade your operating system to a newer version that supports Java 8, or migrate to IBM Business Process Manager V8.5.7 CF2017.06, which is the last version that provides 32-bit Java 7 in the remote migration utility.
