Upgrading Splunk Docker Container from 7.0.0 to 7.2.3

In the following article it says that upgrades from sub 7.2.0 containers to 7.2.0+ containers is not supported. https://www.splunk.com/blog/2018/10/24/announcing-splunk-on-docker.html Is there a way to migrate from an older container (7.0.0) to 7.2.3 even if it is unsupported?
