Hi dezt, I used to work for Westfield then One Connect so have quite a bit of knowledge in this area, If you do only have SIMs application support this will be listed on your SLA as SIMS Software Only Support Service (Plan i) - If this is the case then you can install SIMs yourself however you need to be a bit careful as, if your server then 'falls over' at some point in the future leaving the school with no SIMS system, One Connect will NOT support the hardware without it costing you a small fortune!! SIMS application support covers the software only meaning the elements of SIMS, personnel, finance etc. MHowever they cant dictate to any school where you buy your hardware from, what they can do is insist that it meets Capita's minimum spec otherwise they wont support any of it!! If you need any further info pm me and Ill send it across :-)
