Run the migration utility before connecting the upgraded environment back to the Content Repository. Running the migration utility will ensure all project folder names in the Content Repository change from Database IDs to their Project ID field (from P6).
If you upgraded P6 from a previous version, you must:
- Go to the P6EPPM_Home/p6 folder.
- Run migrationtool.cmd or migrationtool.sh (based on your operating system).
