RPAS MFP - Patch Saved Workbooks from 15.0.0.10 to 16.0.0.5

Hi All

I know Oracle does not support the patching of saved workbooks when upgrading the RPAS platform but.........

We have all but completed patching our RPAS MFP solution from 15.0.1.10 to 16.0.0.5.  We must upgrade in to migrate Weblogic 12.1.3 (Java 1.7 unsupported) to 12.2.1 (Java 1.8).

The problem is we are mid budget and the planners are using their saved workbooks as a kind of versioning.  The introduction of multileveldisplay measure attribute means that all of the saved workbooks cannot be accessed post patch.  Attempting to open one the saved workbooks errors  when the measure attribute cannot be found.

From what I can see, there are no other changes that would prevent access to the workbook after the patch.  This is the only difference I have seen when comparing workbook db files of a saved workbook and one generated in the patched environment.
