magstar 3494 / 3590 / AIX question

[Richard Cowen]

I am currently running:

AIX 4.2.1
ADSM 3.1.2.55
Atape 4.4.0.0
atldd 4.0.1.0
3590 B1A's.

I am going to upgrade the 3590's to E1A's.

The newest drivers are:

Atape 5.3.7
atldd 4.1.5

The question:

Can I stay at AIX 4.2.1 and run these newer drivers?
Smitty install doesn't complain.
I have a call into Support, but its currently in the software<->hardware loop.
