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 Process Manager V8.5.7 on a third computer with the same operating system as the migration source computer (for example, Linux if you are migrating from Linux to Windows). 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.

To migrate from a 32-bit system, run the BPMCreateRemoteMigrationUtilities command on your 64-bit IBM Business Process Manager V8.5.7 system, but use the command with the 32bit parameter when you are creating the files for the source system. V8.5.7 supports 64-bit platforms only.

IBM BPM V8.5.7 cumulative fix 2017.03 or later requires Java Runtime Environment (JRE) 7. If your 32-bit system does not support Java 7, you must either upgrade your operating system to a newer version that supports Java 7, or migrate to IBM BPM V8.5.7 CF2016.12, which is the last version that provides 32-bit Java 6 in the remote migration utility.
