Since you have encountered a corrupted project error, the migration/ upgrade will need to be restarted from the beginning for this project, meaning obtain a fresh and clean copy of the repository and the db components and then start the migration from the beginning. Once these are obtained you will import the db component, correct the ownership with the sql queries to associate the new td user to the current db component. Then you will copy over the clean repository, edit the dbid.xml, and restore to the new instance/version. Next, complete the restore and then you will run the maintenance>verify options and manually correct the issues flagged (from the above statements I would expect to see at least a couple of items flagged as requiring manual correction). After correcting all issues manually, re-run the verify and check that only items being flagged as correctable by the repair function exists, if not correct the manual issues and repeat this step until only repairable by the tool issues exist. Once this is achieved, run the maintenance>repair functions. I would recommend re-running the verify after this and if all is corrected, then you may proceed forward and run the upgrade process, at which time correct completion will yield a correct and upgraded project.
Good luck and if you still experience issues, I would recommend contacting your support carrier for assistance, or if you have no service support provider you may contact Orasi for a contracting to have assistance with your matter.
