Hello,
Did you upgrade from 3.4 or 4.3 ? I am assuming that you meant 4.3 since 3.4 didn't have task scheduling support unless you manually configured the tasks via windows task scheduler.
That being said.
Upgrading from v4.3 to to 4.4 should not cause any unexpected problems with existing scheduled tasks.
Can you please explain how the transfer rules are not working, the rules you've configured and what the expected result should be and the actual result.
You can contact me directly via the
contact us link since I think via email might be more appropriate for troubleshooting this issue.
