Hi,

When I upgrade to a newer version will the upgrade process migrate any running workflows seamlessly onto the new version?

We use activiti in our products. Till now (5.6 -> 5.15.1) there was no issue with the upgrade.

If I am running in a cluster is it possible to have instances at different versions or do I need all instances to be at the same version?

It really depends on the changes made in the newer version. It can be tricky in general.

Regards
Martin

Many thanks for the response Martin.

Would you be able to tell me what steps were involved with upgrade? Also do all of the Activiti instances have to be shutdown while the upgrade takes place or can Activiti still be running?

Hi,
DB changes go hand in hand with code changes. (it really depends on the changes) but we applied the safest way.

Server shutdow
code upgrade
server start (DB is upgraded automatically on the start-up.)
