[Opensource] Transition from 4.x to 5.x

[Tino Dai]

Hi Everybody,

   I'm switching over from Expresso 4.x to 5.x with a mysql database,
and there is some database changes that need to happen. Does about have
an hints about this, or maybe even a script to massage the data into the
5.x for a mysql database?

Thanks!
Tino
