Thanks for the reply!
For example, I have the installation of Activiti 5.6. I want upgrade it to higher version and save runtime data. How can I do this?
Earlier I thought, that I must to download .zip archive with Activiti, unpack it to another (other than 5.6) directory and run demo.start… (In this case all my runtime data was left in version 5.6)
But after you words…
Can you explain in more detail how to upgrade my installation of activiti?
Thanks a lot!
