Copying the migration utilities to the source computer

If you installed IBM® Business Process Manager V8.5.6 on a different computer from your source environment, package the remote migration utilities into an image and copy the image back to the source computer. You will use the migration utilities to take a snapshot of the previous version.

About this task

Important: To migrate to a computer with a different operating system (for example, from Windows to Linux), or to migrate from a 32-bit to 64-bit computer, see "Considerations for migrating to a different operating system or from 32-bit to 64-bit" at the end of this topic. IBM Business Process Manager V8.5.6 supports 64-bit platforms only.

Procedure

On a system that has the new version installed and the same operating system as the source environment, create a remote migration image by using the BPMCreateRemoteMigrationUtilities command from the target_install_root/bin directory. This image must be copied to the migration source computer and is used to create the snapshot.
Use the following syntax:
```
BPMCreateRemoteMigrationUtilities.sh remoteMigrationUtilities.zip
```
If you are migrating from a 32-bit operating system to a 64-bit operating system, use the following syntax:
```
BPMCreateRemoteMigrationUtilities.sh remoteMigrationUtilities.zip 32bit 
```
The location of the remoteMigrationUtilities.zip file is displayed when you run the BPMCreateRemoteMigrationUtilities command. If you specify only the file name and not the full path name, the remoteMigrationUtilities.zip file is created in the install_root/util/migration/scripts directory.
The BPMCreateRemoteMigrationUtilities command does not write to a log file, but displays the results in a window. For example:
```
/opt/BPM85/bin>BPMCreateRemoteMigrationUtilities.sh /opt/MigrationUtility.zip
Buildfile: /opt/BPM85STD/util/migration/scripts/createMigrationUtilDisk.ant
create_zip_image:
[zip] Building zip: /opt/MigrationUtility.zip

BUILD SUCCESSFUL
Total time: 41 seconds
```
After you have run the BPMCreateRemoteMigrationUtilities command, check the generated remoteMigrationUtilities.zip file and verify that it contains the following folders:
- bin
- BPM
- configuration
- etc
- java
- jdbcdrivers
- lib
- plugins
- properties
- util
The bin folder should contain BPMConfig.sh, BPMExtractSourceInformation.sh, and BPMManageApplications.sh.
For more information, see the BPMCreateRemoteMigrationUtilities command-line utility command.
Use FTP, RCP, or some other mechanism to copy the remote migration utility image from the target system to the source system. Then, extract the remote migration utilities into their own unique directory on the source system.
Use the unzip remoteMigrationUtilities.zip command to extract the contents of the compressed file. If there is no unzip tool on the UNIX system, either install the unzip tool manually or use the install_root/java/bin/jar xf remoteMigrationUtilities.zip command to extract the contents.
Important: Ensure that all extracted files have execute permission for the logged-in user. If they do not, use the chmod command to grant execute permission for all extracted files.
Optional: The following steps are required if a custom resource that relies on third-party libraries, such as a third-party JMS provider, is configured in the source environment. The dependent third-party libraries are not migrated, so you must copy them to the target environment manually to make the custom resource work correctly in the target environment. For a migration on the same computer:
1. If the dependent third-party libraries are in a folder under install_root in the source environment, copy them to the same folder under install_root in the target environment.
2. If the dependent third-party libraries are in a folder outside install_root in the source environment, make sure that they are in the same location in the target environment after migration.
For a migration to a different computer:

No matter where the dependent third-party libraries are placed in the source environment, copy them to the same folder in the target environment.
Important: If you are migrating from a Windows system to a Linux or UNIX system, or from a Linux or UNIX system to a Windows system, besides copying the third-party libraries to the target environment, you must also modify the configuration of the custom resource so that it refers to the correct location of the libraries because of the different file path formats of the operating systems.
