according to Chris Jackson's blog you do not have to wait for ACT 6.0:
"ACT 5.5 is ready to go for your Windows 7 migrations (in fact, that’s what
it was designed for). For those of you who are bothered by the “RC” moniker,
well, that’s an easy one. It’s a server-side change, and we’ll be removing RC
from the name around GA. So, hopefully that will defuse that one."
