Both units support the same configuration so you can copy/paste the configuration from 5510 into 5520.
There are some things you need to check for example the ASA 5510 supports either a basic or security plus license which enables the use of Gigabit interfaces on the appliance (instead of 10/100 interfaces with base license).
When you copy/paste the config, you might need to convert FastEthernet to GigaEthernet interfaces (depending on the license).
Both units are basically the same with the difference of capacity for handling connections, VPN tunnels, throughout, etc.
Sensitive things like certificates might be another issue or passwords that will not show under the configuration because the ASA encrypts that information (if you do have that information is just a matter of re-adding the correct values to the new ASA).
More people are working remotely, and this increases the risk of security breaches and the difficulty in defending remote workers where they work and securing the devices they use.
