Without seeing the set up ,position of new boiler,it is hard to give an exact detailed list of what pipework is removed and what is capped or joined together,there are quite a few threads that should give you some pointers

as puddle said without seeing your setup there is no way we can tell you which pipe goes where.

Ok, the new combi is to go where the system boiler is in kitchen, so the flow and return pipes are there. The cylinder is upstairs in cupboard, I know the cold feed isn't needed upstairs so can blank that off, I'm tapping that in downstairs. Then theres the hot feed from the cylinder thats not going to be required in the cupboard as I'm tapping that in downstairs to. So I have the flow and return from the cylinder with three port valve on then pump going back to return side but just after the three port valve theres a 15mm tap off going to what I presume is secondary return. I just need to know what way the flow and return are connected upstairs and what happens to the secondary return, I thought this got capped off, but please correct me if I'm wrong. Thanks

It is quite easy.
Just cut everything out you don't need and join all the bits you do.

Don't want to sound unhelpful, but if you don't know what your doing, you should'nt touch it. Even if the work is for yourself you must be competent to do gas work. If things go badly wrong you will have to answer to the courts. New sentencing laws mean you can get custodial for working illegally.
