"This is interesting. In Yr3, if we just remove the remaining 3590s in the last L12 frame and replace them with bare slots, can the slots hold 3592 tapes? Does it mean the L12 doesn't need to be converted into a L22 before it can hold 3592 tapes?"
My understanding is you only need to upgrade the L12s to L22s if you plan to use them to house 3592s. The slots are capable of holding either media. [EMAIL PROTECTED]
