1. If we don't use LiveSite, can we skip running the tool after upgrade? 2. If we have to run the tool, can we run it later? I ask it because it may take long time for all of workareas, and it may not be finished in the release day. Can we migrate single workarea everyday at night after release day? Whether the new created DCRs can work together with the old un-migrated ones? 3. Can we run the tool for new 7.3.2 DCRs? I wonder what happens if we run the tool for a workarea, which contains mixed 7.3.2 DCRs and old 6.7.2 DCRs.4. After running the tool, it need submit the filies. I guess it means submit to staging instead of publishing to OD receiver. Please confirm it.
