    AP is relocating to a new server Friday Night

    Rick has purchased a new server plan.
    We will relocate this weekend, with the actual switch from 10:00pm Sunday night.

    Relocation plan ... (this will be updated as we progress)

    Completed...
    1. Buy new service
    2. Tell all the members what is happening and when
    3. Ensure domain names set at 60 minute TTL (so new IP address gets propagated quickly)
    4. Setup new technical environment
    5. rsync copy existing site to new server and database (~10GB attachments, comp entries etc) (Friday/Saturday)
    6. Run in test mode on new server
    7. Make sure backups are correct on new server
    To do...
    1. Offline old AP site (Late Friday)
    2. Change DNS to new server change on old server as well
    3. rsync any last changes
    4. Copy database latest from old to new server
    5. Make AP live on new server
    6. Mailout to all member 12-24 hours after go live
    7. Cancel the old service


    As the domain name will take a while to propagate from the old server to the new server
    we will provide the IP address so you can access the new site by setting up a hosts table entry.

    The new server offers us a lot of benefits. We have decided to change hosting companies as well. Whilst our previous hosting company served us well, the site has been growing more rapidly than the hosting service could provide. Thus we have spent some time recently assessing a heap of hosting options and have found one that provides us with a much better service, whilst keeping site running costs to around the same $ amount.

    Good luck for a smooth changeover! If it is, it speaks volumes for your site management skills.

    Just bumping this thread with a reminder.

    Ausphotography will be off-line TONIGHT from about 10.00pm as the site is relocated to a new hosting service, and thus a new server as well. It is expected to take around 2 hours to complete the site migration.

    Members may experience issues connecting to the site after the move. We will update the site Name Servers and DNS registers as soon as the move takes place, but these have to propagate worldwide to every ISP. Until your ISP does an update and collects the new data that directs 'www.ausphotography.net.au' from your address bar, to the new site location, you may experience access issues.

    From past experience some ISP's update their DNS registers quickly and others not so fast. Generally if you cannot get onto AP straight after the relocation, you may find your ISP takes up to 24 hours to update its registers. Please just try every couple of hours and eventually you will regain access.

    The new server offers twice as much RAM, twice as much HDD space (compared to the current site server) and we will be running with a quad core processor.

    For several reasons (social and normal work related = I ran out of time) I've deferred the move.

    Things have progressed well, I'm probably going to do the move Friday night which allows Saturday to resolve any minor glitches.

    New server performance results. (Technical note)

    Our current server has two virtual 2Ghz processor cores allocated via the Parallels Virtuozzo technology and 1.3GB of memory.
    The new server has four 2Ghz virtual processor cores allocated via HyperV (which is XEN like i.e. a bare metal vitualisation) and 2.0GB of memory,
    i.e. double the CPUs and 50% more memory.

    So what have I observed so far?
    • Single threaded tasks are not significantly faster on the new server
    • Multi threaded tasks (Multiple web hits) are handled much better


    This means that performance will be similar but our ability to handle more users at once is better
    (which is the problem we are trying to solve),
    also performance won't degrade as much under heavy load.


    See this technical item that explains why HyperV/XEN is better than Virtuozzo http://hostcube.com/blog/48/virtuozzo-vs-xen/

    The older server will be offline in about 30 minutes...

    The new one will be up within 60 minutes after that, but it may take a while for the name servers to catch up.
