Assuming we're not trying for a "big bang" migration where we move everything at once, it seems we have two main approaches:
1) Assign existing OpenOffice.org DNS to Apache now. For services which we have not yet migrated to Apache we redirect back to Oracle's server, by IP address. As additional services are migrated to Apache, we remove redirects. 2) Do it in the opposite direction: DNS goes to Oracle's servers and they redirect to Apache for services that we've migrated. As services are migrated we ask Oracle to add additional requests. When everything is migrated then we switch over the DNS. #1 seems a lot cleaner to me, and requires less coordination with Oracle. We control the DNS, redirects and generally set the pace of migration. But are there protocols beyond http/https that we need to worry about? For example, any ftp, smtp, nntp, etc. that would complicate things? If we can agree on the general approach I don't see why we couldn't start some migration this week. Bugzilla, for example, seems to be a straightforward. -Rob
