We are currently using X3 v7 and are making preparations to upgrade.  We would like to hear from those who were a part of the upgrade project team for their company and who upgraded to v11 from a previous X3 version, preferably v7 or newer.  We'd like to gain insight into your general experience as well as learn about potential challenges of which we would not have otherwise anticipated.  We are also particularly interested in those who are utilizing the graphical Production Scheduler and the Project And Job Costing functionalities in v11.
