    From The Document Foundation Wiki

    A function that appears in the HSQLDB and Firebird column can already be changed before the migration. An example of this is the combination of several strings: CONCAT as well as the combination with '+' can already be replaced by '||'. This connection works in both internal databases. The further functioning of HSQLDB is not affected by this change.
