Create a full back up of volumes and configuration files that can help you roll back your
upgrade if needed.
About this task
To back up your environment for an upgrade, complete the following steps.
Procedure
- For all patterns, you can back up your environment. For more information, see Backing up your environments in 21.0.3. For more information
on backing up your environment in 22.0.2, see Backing up your environments in 22.0.2.
Note: If your Cloud Pak for Business Automation includes Business Automation Insights, then you do not need
to create Flink savepoints when you are backing up your databases. You can create Flink savepoints
when migrating data from Elasticsearch to OpenSearch.
- For 21.0.3, if you are using IBM Business Automation Workflow Authoring, you must do the following steps. The IBM Business Automation Workflow Authoring database and the Business Automation
Studio database are merged in this release.
- To export your Business Automation
Studio data before you upgrade, run the following command:
https://<bastudio_url>/bas/bpm/explorer/?url=https://<bastudio_url>/bas/artmgt/docs#/Cp4BA%20Migration/migrateExport
- To get the URL to Business Automation
Studio,
run the following command where
<CR_name>
is replaced with the
metadata.name
property from the Cloud Pak for Business Automation
CR:oc describe configmaps <CR_name>-cp4ba-access-info
The
bastudio_url
can be found under the bastudio-access-info
section.
- The
migrateExport
API command redirects you to the Swagger
page. Click Try it out and then Execute. Make sure
that the status is 204 and then open the logs. After you run migrateExport
,
validate that the export is successful. You can also find the exported files and logs from the PVC
that is used to store the Business Automation
Studio server dump files, for example,
<CR-name>-bastudio-dump-pvc
.oc project my_project
oc exec -it `oc get pod|grep icp4adeploy-bastudio-deployment | awk '{print $1}'` -\- grep ended \
/opt/ibm/wlp/output/defaultServer/dump/BasMigration/export.log
In the log, look for the following messages.
–
Defaulted container "bastudio-container" out of: bastudio-container, ssl-initcontainer
(init), pfs-db-compatibility-checking (init), folder-prepare-container (init)
INFO: com.ibm.bpm.bas.migration.BasMigrationOrchestrator - Export
