Upgrade Requirements
Release 26.1 supports upgrades starting with the 24.1 release. To upgrade a store directly to the current release, the store must be running release 24.1 or later.
If you have a store running a 20.x, 21.x or 22.x or 23.x release, we recommend that you upgrade it to the current release by first upgrading to a 24.x or 25.x release. Then you can upgrade to the current release.
If you have a store running a 19.x or earlier release and you are an Enterprise Edition user, please contact support. If you are a Community Edition user with this issue, please post a question to the Oracle NoSQL Database GitHub repository
Note:
Release 26.1 introduced a new store-wide system-level compatibility state which can be upgraded with plan upgrade-scv command.
