How to change a FormVariable type of a process in execution?

So, i've implemented activiti for a company and some process of this company
One process is very long lived one (4 months)

At the very last moment we found that a FormVariable that writes a ProcessVariable has the wrong type
The variable shoud be a double but in the process is a long

How can i change the process definition affecting the already executing processes ?
Is it possible to modify an executing process ?

Thanks in advance

Hi,

Well, that's an interesting one. I'll try and setup a unit test for this to answer your question in a better way.
Right now I would think that updating the processDefinitionId on the running instances is enough. In addition, the history of the process instances should probably be update too if you want to keep that.
But that could be a simple update statement on the database. I'll come back to this after implementing the unit test.

Best regards,
