Have an old, old version of xi 3.1 SP1 - product code 12.1.0.882, need to urgently upgrade to support IE11
Options appear to be upgrade to SP 7 - is this done SP by SP up to SP7 or can SP7 be installed as a 'one off'.
If we chose to go to go directly to Version 4 range 4.0/1/2 - is this a best step and would we install over 3.1 version or need to upgrade 3.1 first.
