Just to note here. In addition to that mentioned by my colleague above, while you can upgrade to an older version, we would not recommend it. Our recommendation would be to test with the 4.6.10 release, and address those issues. This is because if you do the live upgrade and do it to 4.6.9, and Something goes wrong, our advice would only be to revert and use the latest release. We wouldnt assist with issues you have in upgrading to an older release
