If I had a F5 system running LTM feature, after I buy more ASM feature.
How do you do active more ASM license ?
I need add on Base Registration Key or Add-on key ?
If use Base registration Key >> after active Do you know F5 lost old LTM feature ?
If you purchage ASM feature in exiting F5 Software then add key under ADD-ON key. Add-on key length will be 14digits[i.e AAAAAAA-BBBBBBB]
I will suggest to avoid activating any license in prod hours. As it will start unix deamons. Follow the instructions per F5 recommended doc.
