This is the standard behavior to migrate data. But I consider this a bad approach when I´d forced down to it. If some feature you use disapears from your hand, the minimum efort to preserve data must be done by developers.

My applications relly on streams. Now I will need to sneak over COS and classes to migrate my own data to the new datatype. This is bad!

Thanks Bill;

This brinks up some relief. We´ll migrate the data later in the schedule.

With %Library.GlobalCharacterStream I can simply manipulate the streams with SELECT, INSERT, UPDATE ou DELETE SQL commands. Treating the stream field like a string one.
