Deleting migrate module tables post migration We did a massive migration a while back, several hundred thousand rows. Needless to say we now have a bunch of migrate tables that we could do without. 

I've disabled the migrate modules but before I dropped the tables (or should I truncate?) I wanted to make doubly sure that this will have no affect on anything.

Thanks in advance.
So, I deleted the tables (actually truncated them) on my dev server and there have been no side effects that I have noticed, so will try deleting the tables in their entirely. The migrate tables made up around 600mb in a dump.
