Ok, so now that we made some progress on our Bakery, I am finally able to get back to citadel.
I am setting up a machine which can host my tests both with an existing dataset, and without so that I can test an upgrade with 300 + accounts and also a new install. This will all be LDAP. Any gotchas I need to know about how the data is going to be handled, and also, is it currently set on upgrade to take the existing GAB and then populate the mail table with that? How is it currently?
