Questions[groupwise](server)

My employer has recently moved from Novell GroupWise 6.5 to Exchange 2010. We've imposed mailbox limits on staff but we still need to move their old messages, contacts, calendars, etc. over to Outlook 2010.

Our problem however is this, utilizing the Novell MAPI client is slow within Outlook 2010 and upon exporting messages to a PST file (for later re-attachment, and offline backup purposes) crashes the GroupWise server. Connecting to the server in Outlook via IMAP to export messages to PST is faster and apparently more stable but also crashes the server.

We'll be keeping our GroupWise server online internally until then end of the year but I have staff with mailboxes approaching 12 gigabytes, which is fine if we're going to move the data to offline storage (DVD set) but if I keep crashing the server every time I try to get the data I'll just be spinning my wheels. In my first attempts, I tried to move mail for a staff member with 3GB of data. The transfer lasted roughly 8 hours before crashing.

I'm wondering if there is an open source solution to my problem. Paid solutions exist but we're a not-for-profit organization and have too many staff to justify the costs of per seat licenses just to migrate mail.

Every time I restart my Novell Groupwise on Suse Open Enterprise server the root certificate goes missing. Thats why ldap is not starting and so the other services are not working. After repairing the cert on the second server via imanager everything works fine, until the next restart. This only happens on the first server. The second restarts without problems.

I'm attempting to move a GroupWise POA from a crippled SLES cluster to a 2008R2 server, it appears all the binaries meet the requirements, but where the documentation fails me are for a few questions:

1) Is a local installation of eDirectory required on the Windows server?

2) There are references to using a DBcopy utility when migrating TO Linux due to filename case changes, is this a concern going the other direction? I suspect not.

So.. my email server's send queue is currently at 20,000+ emails and growing. Log files are full of this type of thing:

Port 25 on the firewall is set up to allow connections only from our anti-spam provider (postini)

My question is, how do I find out where these messages are originating, and how do I stop them?

I'm curious as to how much time it takes to transition 1K email (~200mb/acct) accounts from a locally hosted groupwise 7 mail server to a 2010 exchange server hosted in the cloud. Can you transfer over all old email and contacts? Is it possible to manage this transition so that users can have continuous access to their email? Our bandwith to the internet is 100mbps.

My organization is making this transition—we're a school. Email must be down for 5-7 days to allow for the transition. I'm told by IT that it has to be this way. It sounds like this isn't true, correct? Email could be kept up continuously, and the transition could be done much faster?
