That page is not very clear to me, doesn't say what was tested exactly.

The services provided by current OSGeo6 are:
https://wiki.osgeo.org/wiki/Osgeo6#Services_hosted_on_osgeo6

  - Mail Submission Agent
    https://wiki.osgeo.org/wiki/SAC:Message_Submission_Agent
    To test:
      - ability to SEND email from an @osgeo.org
        (@staging.osgeo.org while staging)
        using the OSGeo UserID credentials.
      - Mail authentication (SPF/DMARC/DKIM)

  - Mail Transport Agent
    https://wiki.osgeo.org/wiki/SAC:Message_Transport_Agent
    To test:
      - Ability to receive mail sent to an @osgeo.org alias
        (@staging.osgeo.org alias while in staging)
      - Mail evaluation (DMARC/SPF/DKIM)
      - Spam handling (graylists etc.)

  - Mailing lists service
    https://wiki.osgeo.org/wiki/SAC:Mailing_Lists
    To test:
      - Ability to create a list, subscribe, send to and
        receive mail from the list, via mail.
      - Ability to see archives and login via web form.

  - The www.tilecache.org website
    https://trac.osgeo.org/osgeo/ticket/3407
    To test:
      - Ability to still reach it (unless it's dismissed)

  - MySQL ?
    This is found on the wiki but it isn't clear if the service if needed
    can we drop it safely ?

The Trac mail setup is a bit confused at the moment in that some
projects use "localhost" as the mail server and other
"mail.osgeo.org", I've just filed a ticket to simplify it:
https://trac.osgeo.org/osgeo/ticket/3436

The tracsvn postfix service doesn't have any special configuration to
be trusted more than a normal SMTP connection so the ability to
connect to port 25 of the new IP and send mail via it should be enough
as a test.

Better do this now, if not needed, less confusion later.

> - On osgeo9: Make a final rsync with osgeo6

My understanding is that the current "rsync" doesn't sync all the data
on the disk, but just a subset, could you tell which subset of data
and configurations are synchronized ?

In particular, do we get queued email ?
At the moment osgeo6 has 2079 queued emails.

I think we need to figure out how to ensure no queued mail gets lost,
so a way to have the NEW service process the OLD queues, or keep the
old service alive until it's finished with those queues while not
accepting new ones...

Is there anything in the new container that should be DIFFERENT
from the old container ? Otherwise why not just rsync everything ?
