Hi,
I'm currently trying to migrate a client's Mingle 3.2 on Windows to 3.3 on Linux. Unfortunately, although one of their Mingle 3.2 projects imports successfully, their most important one fails with the error "Error while processing import, please contact your Mingle administrator. Upgrade failed, please contact Mingle support"
Attached to this ticket is the stack trace in the logs - can anyone explain why it failed or how to remedy this?
