Hi,i try a upgrade from old 3.0.3 Kamailio mysql db. Got stuck with update the structure :ALTER TABLE rls_presentity MODIFY callid VARCHAR(255) NOT NULL; ALTER TABLE rls_presentity MODIFY contact VARCHAR(128) NOT NULL;But this two table does not exist? See also table definition at: https://kamailio.org/docs/db-tables/kamailio-db-3.1.x.html# GEN-DB-RLS-PRESENTITY I reckon it is safe to skip this to tables?Kristijan
