Vaults and upgrademanager
When the upgrade manager runs, does it actually do anything to the physical vaults on disk? I know there are some pointer updates in the Oracle database that get touched by the upgrade and that is fine.
My reason for asking is that I have run a WC11 upgrade on these same vaults. Deleted WC11 and the Oracle DB from the first run and am doing a second run and am ready to run upgrademanager when I remembered that these vault folders have been through an upgrademanager routine before.
I do have a copy of the vaults as they came off the production system, but I do not think I saved an extra copy from the WC10 rehost system. Again, talking only the physical disk vault files. I have compared the file size and it has not changed from the original copy from production.
