Hello,
It would be better if you had kept the same storage configuration for your new TL. It seems you have all the "old" tapes assigned to the storage named TL2000 and you had configured a new storage named "TL4000". The MediaIds from 2065 to 2112 are assigned to the TL2000 storage.
To have these medias assigned to the new TL4000, I think you should do this manually in the catalog database:
1) Look for the StorageId in the Storage table that refers to your new storage TL4000.
2) Set the StorageId value in the table Media with the StorageId number you found in step 1) for all the MediaIds from 2065 to 2112
This is possible since you haven't changed the Media Type.
If you're using MySQL, you can do the bellow:
1) select * from Storage; (this will show you the StorageId for Name=TL4000)
2) update Media set StorageId=X where StorageId=Y (where X is the value of StorageId for TL4000 and Y is the value of StorageId for TL2000).
Best regards,
Ana
