Merging of QMS with Advisera template

We have our own qms outdated as far as procedures is concerned but the specs and forms are being used ervery day. Then we have the version bought ad advisera that could be merged somehow. But we have also a lot of stand alone procedures that are better or more suitable than no 1 and 2 merged. Actually it’s more like merging 2,5 qms where some cherry picking should be done. This merging is something that I would like to ( partly) outsource. Furthermore i am wondering if we should wait for this before we upload to conformio. We would be best served with document control ASAP regardless of current state of procedures. In short: merge first and then upload or upload and then merge. If you could tell us what best practice is, it would be very helpful.
