Restoring from old LTO3 tape drives

I was running a server with Backup Exec 10d with an LTO3 drive, now I have a server thats running Backup Exec 12.5 with an LTO 4 tape drive.  The other server and tape drive was a least so I now have to return the equipment. What I want to know is will I be able to restore from the LTO3 Media I backed up to with the LTO 4 drive with the BE 12.5 that I currently have. If so will I need all the old Catalog files from Backup Exec 10d.

 if you go to Tools>Options>Catalog and uncheck (temporarily for the duration of the cataloging) "Storage media-based catalogs". It will take a long time to catalog each tape, but you might be successful. You might also consider changing the catalog directory there too so as to rule out corruption. Here is what found written about storage media-based catalogs:
"Select this option to allow Backup Exec to read the catalog information from the media.
Media-based catalogs allow quick cataloging of media that are not included in the disk-based catalog (for example, media that was written by another installation of Backup Exec). This feature enables media to be cataloged in minutes, rather than the hours required with traditional file-by-file cataloging methods.
If you want to create a new catalog by having Backup Exec read each file block, clear this option. Clearing this option is only recommended if normal catalog methods are unsuccessful.
If you uncheck Request all media in the sequence for catalog operations, then the Use storage media-based catalogs check box cannot be selected.
You cannot use Granular Recovery Technology if you select this option."

Depending on how you are upgrading from 10D to 12.5 the above two links will help you in getting an in-sight.
You shouldn't have any problem reading LTO 3's with your LTO 4 drive.

If you've still got the old server, have you considered making an image of the hard disc, running it on your new machine, upgrading the old BE installation to 12.5, then copying the files from the new BE installation into your new server/s original disc? That way you'd retain all your media catalogs, and wouldn't have to pull them off the tapes.
