Flowable community edition upgrade/down grade

Sometimes before when i tried to upgrade from 6.0.0 to 6.6.0 after that spring service not started until i created new schema. In flowable community edition, is it possible to upgrade and downgrade version when using with spring-boot.
Please let me know. Thanks in advance!

Very possible to upgrade. Just stop your spring boot server, update your maven/ant/gradle (whatever you use) to use the newer Flowable version, and then spin spring boot back up. It’s one-way though. Once you upgrade, you MUST use the newer version. Also, pay attention to the Spring versions within the Flowable build. You may need to upgrade ALL your dependencies in order for a newer version of Flowable to work properly.

Generally speaking, there shouldn’t be many cases where you have to flip-flop between versions. Also consider that anything earlier than 6.7 contains a Spring vulnerability with a CVE score of 9.0 so you really want to ensure you stay up to date on it and run 6.7 or later.
