We have discovered that, after an upgrade to 7.1, there are quite a few OLD DW4 files. I did not realize their documents went back that far, until a user tried to access one today. My understanding from the support ticket I opened is that 7.2 WILL support DW4 documents. However, I didn't get a clear answer as to whether the upgrade to 7.2 will resolve the issue, now that we have upgraded to 7.1. I have their old system (6.7) on a different server, but with the amount of docs, I prefer not to export them out and re-import, if the upgrade to 7.2 will fix it. Is that the case, or are they now corrupt in the existing database?
