Any JPA features for updating table metadata without loosing existing data?

Hi there,

I'm having a database with live data in it.

Now i have to change some tables (add columns, etc.). How can i do this without using drop-create-schema mechanics?

Do i really have to change my entity classes first, change schema creation to just create-schema so that only new tables are created automatically and finally have to put all the "alter table" stuff manually?

Is there any better solution?

Thanx in advance
