So in this case how is it possible to migrate data form  the old database to the new one. In fact i have two different versions of Galaxy installed in my machine and I don't want to loose data like histories that I creted in the old version one.
Thanks for help

The main problem with different versions of galaxy is that the database schema that they expect (as applied by versioned migrations from the galaxy codebase) is different.  So you could end up working with a database that has fields and keys you aren't expecting, which would be bad.
