An important on migrating Developer Portal OVAs from Ubuntu V16.04 to Ubuntu V18.04:  It is strongly recommended that you migrate your Developer Portal to Ubuntu V18.04 because support for Ubuntu V16.04 is being withdrawn in March 2021. To migrate your Developer Portal OVAs from Ubuntu V16.04 to Ubuntu V18.04, you need to perform a backup and restore method of migration. This method involves backing up your current Ubuntu V16.04 Developer Portal content, standing up new OVAs on Ubuntu V18.04, and then restoring the Developer Portal content onto the new OVAs. See the following link for details: https://www.ibm.com/support/knowledgecenter/SSMNED_5.0.0/com.ibm.apic.install.doc/tapim_portal_production_migrate_ubuntu18.html
