Hi there,

We are trying to upgrade our on-premise installation from 7.11 to 16.1. Following the upgrade guide, we made sure not to miss upgrade aspects such as:
- primary data store having a different property name
- replacing static content of the webserver
- upgraded configuration files / web.xml / topology etc.

We are running the Appian server on JBoss EAP 6.4.0 on IIS with MySQL connector 5.1.38-bin.jar. Previously, upgraded from 7.9 -> 7.10 -> 7.11 and last version ran perfectly fine.

After upgrading to 16.1 we can't access the records, the design has a "sysrule.appdesigner.filter.search" message (see screenshot below). In the attachments the server.log is there. We tried going through the upgrade process several times and re-downloaded the 16.1 installer.

Main error we get is:
12:07:26,952 INFO [stdout] (ajp-/0.0.0.0:8009-1) 2016-02-22 12:07:26,947 [ajp-/0.0.0.0:8009-1] ERROR com.appiancorp.expr...
