NetBackup 7.0.1 First Availability (FA) Program
IS THIS AN ALPHA OR BETA PROGRAM?
No. First Availability software is production ready GA software that has passed stringent Symantec release and quality criteria. This is not an Alpha or Beta program and we encourage and fully support FA code in production environments. The First Availability program provides GA quality software to you as soon as it becomes available.
If you want to upgrade to 7.0.1 you'll have to either:
a) wait until GA becomes available; or
b) register for the FA program (that link is available in the above URL also).
