Hi all,
I thought I would add in some "post-migration" comments in case someone else comes across this post.
We ran into a major glitch part way through. Here is what we did simplified:
1) set up new server "MailTemp" which was our "temporary" new server with Dom 9 on it; it would later be renamed to "Mail"
2) we enabled DAOS on the new server and replicated all the mail files over to it
3) with DAOS enabled, as the messages moved over to the new server, the attachments were removed and stored in DAOS
4) after the final replication (and stopping mail moving about the domain), we took the old server off line and renamed the new server to the old server's name (we wanted to do this to avoid having to make other changes external to our company)
5) when we fired up the new server under the original name, we could not open any attachments stored in DAOS
- those who know more than me will recognize the problem immediately - the DAOS attachments were encyrpted with the new server ID of "MailTemp" and so once we switched back to using the original server ID, it could no longer open the attachments.
So we had to start over late at night when we thought we should have been done.
- what we should have done is one of these methods:
A) use OS copy to copy the mail files over onto the new server then rename the server and open them; leave DAOS off so no extraction of attachments happens or
b) leave DAOS turned off and replicate all the mail files if we really wanted to go that route; once the cut-over is done and then the server renamed, turn DAOS on and use "compact" with some switches to get DAOS going on each mail file
Amy Knox (in this thread) was probably hinting at this problem when she put in the note about upgrading from 8.5 to 9.0 but I did not think it applied to us so I did not dig further. If she sees this posting and is able to provide a better workaround, that would be great!
Thanks,
Albert Gostick
