you don't specify where or what the styles are.

If they were presets, all you need to do is download them from www.technicskn7000.com for free. You have the choice of composer or custom format. That will save you a lot of work.

If they were commercial style disks in 5000 format they will load straight into the 7000, they may need the occasional tweak but the pattern information will all work. If you want customs, then copy from composer to custom on the 7000.

If they are in 5000 custom format you need to copy them to composer on the 5000 first and then save them normally, then they will simply load into the 7000 the same as the commercial style disks. If you want customs on the 7000 copy from composer to custom again.
