We don't support Tomcat 7 in custom mode actually hence the error. You would have to switch to express mode (which is much robust and faster). The tim-tomcat-7 there is just fitting code pattern rather than real support.

Currently use terracotta 2.5 with instrumented classes, which the best approach to do the upgrade and pass to express install??

I don't have the answer to best approach but to start, this is the place http://terracotta.org/documentation/web-sessions/installation-guide

In general, if your objects are POJO, you no longer need to instrumented them. In express mode, to store anything in clustered session, the objects (attributes) must be serializable.

You'll find out if something in your session isn't serializable since you'll be rewarded with a NotSerializableException (although it will most certainly be wrapped inside some type of RuntimeException)
