How ASDM Works with the ASA 5506

[joand3512004]

We have just received 18 ASA 5506 swap from the 42/82 RV's installed on our customers. Currently the role of the RV is to be the LAN gateway of the AP's, Loadbalancer, and VPN with the matrix of Oi for management.
Now, as we know little about ASA5506, I wonder how ASDM works for management? Do I need to install multiple ASDMs, or can I install "only" one in a Data Center to manage all the other ASA's?

What I need to do? I downloaded the file in the .bin format, but I do not know how to proceed, I read that I would have to access an ASA, download the file and install it on the PC. But my idea would be to install ASDM on a server, to concentrate or manage others, is it possible?

You need only 1 ASDM to manage all ASA make sure all are in same version. 

Another thing you need to conenct each device seperatly push the policies. but 1 ASDM installation is good for you.

First you should make sure that you are heading in the right direction. Yes, you can install a single ASDM on a server (ASDM-Launcher). But the ASDM is a single-device manager. Each device has to be managed individually. If you want central management because all devices share a similar policy, there are multiple ways to achieve that:

1. Manage all ASAs with the Cisco Security Manager or a similar system from another vendor.
2. Convert the ASAs to Firepower Thread Defense and manage all devices with Firepower Management Center.

Thanks for the information, I'm going to study the best option.

CSM is good Option, if you looking to push the policies Centrally, again for diagnosis you need to rely again on ASDM for Monitoring.
