Lync 2010 migration - when do I introduce Lync Edge and when do I retire OCS Edge

I'm in the middle of migrating from OCS 2007 to Lync 2010
Lync 2010 is up and running through OCS 2007 Edge.
How long should I wait before installing Lync Edge?
And should Lync edge and OCS 2007 edge co-exist until all users are moved to Lync server?

thanks ---
looks like we found several free public IPs we can use.

But once more to DNS configuration.
We currently use:
sip.domain.no - for remote access
av.domain.no - for audio/video
conf.domain.no - for conferencing

Should I use different URLs for Lync?
access.domain.no - remote access
lync-ad.domain.no - audio/video
webconf.domain.no - for conferencing

When creating srv record for sipfederation and sip - i need to choose either Lync or OCS edge, and if I choose Lync i need to configure OCS clients manually, and vice versa?

Okay --- thanks. All good to go now.
I've deployedthe edge server, and let the few Lync users connect manually - letting legacy users use autodiscovery.

And will switch over when all is done.

Thanks
