I have seen similar questions but with not a lot of answers for the ASA platform.
As the title states, how procedures can I use to copy a pre-existing configured CISCO ASA 5520 to a brand new CISCO ASA 5520.
I have found a URL that seems to answer some questions but not all.

Is there any documentation or shorter procedures for product specific on the 5520?

Well, in essence it comes down to this:

Set up a tftp server.

Do the following:

Backup and Restore the Single Mode Configuration or Multiple Mode System Configuration

In single context mode, or from the system configuration in multiple mode, you can copy the startup configuration or running configuration to an external server or to the local Flash memory:

Note: When you copy a configuration to the running configuration, you merge the two configurations. A merge adds any new commands from the new configuration to the running configuration. If the configurations are the same, no changes occur. If commands conflict or if commands affect the running of the context, then the effect of the merge depends on the command. You might get errors, or you might have unexpected results.

Select and copy the startup configuration or running configuration to an external server or to the local Flash memory:

hostname#copy {startup-config | running-config}
tftp://server[/path]/filename
Issue this copy tftp command in order to restore the file back to PIX:

hostname#copy tftp://server[/path]/filename {startup-config | running-config}


So its just a copy to/from a tftp server. If it's brand new (so a default config), you shouldn't have any issue with overwriting/merging existing configs because it isn't there yet.
Please note that this will only copy the configuration, not software or anything else. If you need an exact copy, with AnyConnect, CSD, XML-files and what else might be configured, it's usually easier to the a backup/restore via ASDM: http://www.cisco.com/en/US/docs/security/asa/asa83/asdm63/configuration_guide/admin_swconfig.html#wp1243681
