ASA upgrade

Hello friends

I want to upgrade from ASA 8.x to 9.x.

What are the advantages of upgradation of ASA from 8.x to 9.x?
Is there any drawback of ASA 9.x according to security, performance?

ASA Software Release 9.0

ASA Software Release 9.0 provides several enhancements. Major new features in this release include:

  • The ability to join up to eight Cisco ASA 5585-X or 5580 Series adaptive security appliances in a single cluster, for a linear, predictable increase in performance while providing high availability for always-on data centers
  • Integration with Cisco Cloud Web Security (formerly ScanSafe), which  allows enterprises to enforce granular web access and web application policy while providing protection from viruses and malware
  • Cisco TrustSec® Security Group Tags (SGTs), which integrats security into the network fabric to extend the policy construct on the ASA platform
  • Next-Generation Encryption, including the Suite B set of cryptographic algorithms, for much better confidentiality
  • IPv6, including critical IPv4-to-IPv6 translation features, enabling ASA to be deployed in a mixed v4/v6 environment
  • Dynamic routing and site-to-site VPN on a per-context basis, providing much better segmentation between departments or between customers
