Can I migrate Customer Portal (CP) to the latest version?
Customer Portal (CP) versions in relation to Oracle B2C Service (OSvC) versions
The version of Customer Portal (CP) you can migrate to is limited by the version of Oracle B2C Service (OSvC) currently in use. For example, if your B2C Service site is running on August 2018 version, you can migrate to CP version 3.7. In order to migrate to CP version 3.8, you must upgrade your B2C Service site to August 2019 version or newer.
The following table shows CP release versions: B2C Service Version CP Version CP Version Status August 2019 3.8 Most current CP version August 2017 3.7 February 2017 3.6 August 2016 3.5 Deprecated May 2016 3.4 Deprecated
