We are currently running a production server at version 5.1.2 which we are planning to upgrade.
Tests have shown that upgrading to 5.3 works as expected.
However, upgrading from 5.1.2 -> 5.4 or 5.1.2 -> 5.3 -> 5.4 results in all quality profiles from the 5.1.2 instance becoming empty - no rules assigned at all.
Worse, backing up the rules and attempting to restore them fails silently.
Has anyone else experienced this? Is there a work-around?
Thanks in advance.
