Hello Rüdiger,
to migrate from 1.5 to 2.0 you should execute some SQL commands.
We are working on a small java executable for the futur migration change.
Unfortunatly we didn't had the time to make it for this release.
Have fun with the 2.0...
the script is given here
--
-- CAS UPDATE
-- create the new users table
CREATE TABLE casusers_ AS SELECT username_, passworddigest_ FROM user_;-- update the old users table
ALTER TABLE user_ RENAME TO profileresource_;
UPDATE node_ SET bindedresourceidentifier_ = replace(bindedresourceidentifier_ , '/User/', '/Profile/');
ALTER TABLE profileresource_ DROP COLUMN passworddigest_ ;
ALTER TABLE profileresource_ ADD COLUMN infos_ bytea ;
ALTER TABLE profileresource_ RENAME username_ TO id_;
ALTER TABLE profileresource_ RENAME jabber_ TO jabberid_;-- create guest profile
INSERT INTO profileresource_ (id_, fullname_, email_, jabberid_) VALUES ('guest', 'Guest', '', '');-- init users profiles
UPDATE profileresource_ SET infos_ = '\\254\\355\\000\\005sr\\000\\021java.util.HashMap\\005\\007\\332\\301\\303\\026`\\321\\003\\000\\002F\\000\\012loadFactorI\\000\\011thresholdxp?@\\000\\000\\000\\000\\000\\014w\\010\\000\\000\\000\\020\\000\\000\\000\\000x';
