RE: Upgrading BIGIP-LTM 10 to 11

Unless you have days on hand to reconfigure your boxes, then there is no issue. I have LTM 10.2.3 and tried to upgrade to 11.x four times and the same result every time. It doesn't work. The configuration doesn't carry over and load. Then any external script needs to be reloaded and then once that's done, the entire configuration needs to be re-written from scratch. In addition, all HA configuration needs to be re-thought of and re-written.
