Complete the following steps to prepare the appliance for migration:
Verify the health of the database by running ZDC. Depending on your ZENworks version, download the ZDC from the Micro Focus Download site. For more information, see Downloading and Extracting ZDC in the ZENworks Command Line Utilities Reference.
Ensure that at least 40 GB of free space is available in the /vastorage disk for ZENworks 2017 Appliance.
If you are using Sybase database, then migrate the data to PostgreSQL before migrating to ZENworks 2020. For more information, see the Database Migration from Sybase to PostgreSQL document.
Run the novell-zenworks-prereq.zip to prepare and copy the zone properties for the appliance migration.
NOTE:If Vertica is enabled in the zone, then the microfocus-zenworks-prerequisite.sh script stops the Vertica cluster and the functionality related to Vertica will not work until all the Vertica enabled Appliances are migrated to ZENworks 2020 Update 2. Hence, it is recommended that you run the microfocus-zenworks-prerequisite.sh just before starting the migration process.
Download novell-zenworks-prereq.zip from ZENworks 2020 Download site.
Extract the novell-zenworks-prereq.zip
Copy the novell-zenworks-prereq.sh file to a temporary location on each ZENworks 2017 Appliance Primary Server.
Log into the ZENworks 2017 Appliance Primary Server with root user.
Add the execute permissions by running the chmod novell-zenworks-prereq.sh command.
Run the sh novell-zenworks-prereq.sh command.
Power off the ZENworks 2017 Appliance.
Copy the ZENworks 2017 Appliance virtual disk (vastorage).
It is recommended to copy the ZENworks 2017 Appliance virtual disk and attach it to the ZENworks 2020 Appliance. Ensure that you maintain the same folder structure in the ZENworks 2020 appliance.
NOTE:If the novell-zenworks-prereq.sh is not executed properly, or volume is not copied to the ZENworks 2020 Appliance, then an error message will be displayed.
