if you used no compression or software compression, you should have no problems reading or writing to those old tapes
If you did use hardware compression, you may or may not have any problems. If you do, then if you insert a tape, inventory and then (on he devices tab) right click the drive and choose label, the old data will be unavailable, but you should be able to write to them using the new drive

At one point different manufacturer's HW compression algorithms varied. I haven't checked recently, but since all LTO drives are basically Quantum hardware, you may be able to read the old tapes
All you can do is try it. if it doesn't work, it doesn't work. You may need to keep the old drive around (connected to the new media server) and use it only for restores, and do all your new backups on the new drive
