Hi Lisandro,
Never use the console MySelf but if you look at the manual, link provided in this post : https://forum.avast.com/index.php?topic=124140.0
You will find yourself the answer in the Enterprise Administration Console User Manual
The SQL Data base, the Avast Client and the console are linked to the EAS.
So, I beleive you can have as many console you want…
It’s just like opening a website
Just tell us want you find, I’m curious too.
