Dear Alex, Any ways to migrate from 3.8 to 4.2 directly. I have around 150 tables. I cannot depend upon direct sql import because i have type hierarchy ,where my base table has "Id" and "TypeId" which are auto generated , so i will have to create my own import utility which can do this job for me.

please suggest if you have some other solution. i want to keep migration from old to new application as simple and quick as possible with practically no loss of data.

thanks

You're only talking about the data migration. How did you convert your model from 3.x to 4.X?

Thanks Marco

One Answer:

There is no any intagrated option for this. Other options are listed here: viewtopic.php?f=29&t=5879

Model migration is, likely, less complex problem, if you don't use the infrastructure intensively (e.g. event-like methods in DataObject type and so on). Otherwise you'll need to care about conversion of old patterns to new ones. The good thing here is that behavior of Entity in v4.0 is very similar to behavior of DataObject in v3.X. But method names and almost everything else is new.

Have you automated the model conversion for other projects? or just rebuild from scratch?
