Particular temporary files are generated during an upgrade of Oracle VM Manager from releases prior to 3.3. These files are useful to Oracle Support in a situation where an upgrade fails to complete successfully and the Oracle VM Manager database has not been adequately backed up prior to attempting upgrade. For this reason, they are not removed automatically as part of the upgrade process. These files contain information about the Oracle VM deployment that should not be left in temporary file space indefinitely. Therefore, it is appropriate that you remove these files after you have verified that your upgrade has completed successfully and that your environment is behaving as expected. Instructions are provided in Removing Temporary Files After Upgrade in the Oracle VM Installation and Upgrade Guide.
