I do not understand the problem. The http command you've shown is simply creating a collection. What does that have to do with migrating from c1 to c2? In fact, it is recreating c1. Assuming you haven't redefined the <uniqueKey>, then the router field defaults to "id". So this is just recreating a plain-vanilla collection. If you already have a "c1" collection, I expect the above would simply fail.
There's nothing indicating you tried to move docs from C1 to C2 as the title of this e-mail indicates. There's no magic here, Solr collections are completely independent of one another. If you want docs to be moved, _you_ have to move them.
