Breaking changes

Background

When changing from Workflow Manager to ZerFlow most things will work just as you expect, and in most cases a lot better, so the upgrade will be largely seamless. There are a few excpetions though where ZerFlow engine behaves slightly different from Workflow Manager and we will list all things you need to consider when upgrading and what you need to do in order for your services to work just like before.

Old behaviour	New behaviour	Required action
DateTime variables are no different than String variables	DateTime variables in ZerFlow are handled according to ISO 8601 (YYYY-MM-DDTHH:MM:SSZ)	If you're using string methods when converting/transforming datetime values these could yield unexpected behaviour. You might have to replace them with DateTime manipulation methods
-	New network ports utilized by ZerFlow	Port for Zervicepoint Zebra API and ZerFlow Workflow API needs to be excluded from firewalls and the like
