Best way to get new sump/skimmer going?

[DanG]

I'm just finishing the plumbing and am now starting to think about the best way to get my skimmer going.

It's built into the sump. I am due for a water change in my old tank and was thinking about just dumping in the water I take out of there into the sump for the skimmer to work on, or my other idea was to take the skimmate my old skimmer has collected and dump that into the sump with a batch of NSW.

Or is there a better way to do it?
