Delete old catalogs

Hi

We had a storage dataloss on our deduplication storage. We created a new storage to host a new deduplication storage.

As Backup Exec can only host one deduplication storage, I needed to delete the old one from the interface. It never really finished. The old deduplication storage disappeared from interface, but delete task was still running after a few hours.

I was able to create the new deduplication storage and restart backups but old catalogs are still there as delete task never finished.

Is there a way to delete old catalogs to prevent Backup Exec to show me that I can restore Data that dont exist anymore as old dedup storage was lost ?
