Evaluation Netbackup 8.0

Dear community, as I already posted here https://vox.veritas.com/t5/NetBackup/Netbackup-solution-for-a-global-infrastructure/m-p/830546#M226130

We are planing to move to Veritas, I would now want to conduct a POC, regarding this I have some questions.

1. Is it possible to dowload the NBU Master server 8.0 and use it in Evaluation for 30 Days or so?
2. If possible, where can I download the Software.

3. I also need to download 2 Media Servers for the test.
4. If possible, where can I download the Software.

5. I also need to download A.I.R to test it.
6. If possible, where can I download the Software.

7. In this regards, I also need to OST Eval Licensing, is this also available somewhere?

Thanks for the help.
Best regards,
Marco
