Recently, while converting a client from P6 r8.3 to r15.2, we had to move a number of baselines to the new database. We used our P6-Loader to unassign and detach the baselines from the current project and then created XER’s to move them to the new database.
To our surprise, when we imported the baselines as projects into the new 15.2 database, the WBS elements were all messed up. Instead of one project with many WBS elements, our project appeared as many different projects, one per WBS, all with the same Project ID. They also appeared outside the EPS structure and P6 wouldn’t let us move them into the correct EPS node. Every attempt gave us the error that “ is not a valid integer value”.
