Best practice: Case instance migration using database commands

Hi All,

I have some running cases in an old case definition version. I deploy a new case version and I would like to point all old cases to this new version.

I understand that I only need to change the table ACT_RU_CASE_EXECUTION, updating the case_def_id_ collun to the new version id, from ACT_RE_CASE_DEF table.

After that, start camunda. I am using Tomcat.

Is it correct ? Are there some risks, considering the process are compatible ?
